Answer:

x = 85

Step-by-step explanation:

Step 1: Solve x

∠x = 180 - 27 - 68

∠x = 85

Therefore angle x equals 85

Answer:

85 degrees

Step-by-step explanation:

The sum of the angles of a triangle always add up to 180 degrees.

Here, we have two angles already given, so we can write:

27 + 68 + x = 180

95 + x = 180

Subtract 95 from both sides:

x = 180 - 95 = 85

The answer is thus 85 degrees.

Answer:

9^3

Step-by-step explanation:

9x9x9= 729

Start by setting up your two sets of parenthses.

Inside, we have the terms that compose each binomial.

Since x² breaks down into x · x, we use an x in each binomial.

The second term is the factors of -12 that add to the coefficient

of the middle term but what is the coefficient of the middle term?

If there is nothing written there, it's understood to be 1.

So factors of -12 that add to -1 are 4 and -4.

So we have (x + 4)(x - 3) which is our answer.

Answer:

x = 4 , x = -3

Step-by-step explanation:

x^2 - x - 12 = ( x - 4) ( x + 3)

x - 4 = 0 or x + 3 = 0

x = 4 or x = -3

Answer:

In the given quadrilateral, two angles measure 60° and other two angles measure 120°.

Step-by-step explanation:

As we know sum of all interior angles of a polygon with 'n' sides is,

Sum of interior angles = (n - 2) × 180°

                                     = (4 - 2) × 180° [for a polygon with n = 4]

                                     = 360°

a + a + 2a + 2a = 360°

6a = 360°

x = 60°

Measure of angles = a° = 60°

And angles having measure = 2a° = 2(60)°

                                               = 120°

Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.

Answer:

65

Step-by-step explanation:

TAB is an isosceles triangle by the point to tangent theorem theorem.

BAT and BAT are congruent because of the isosceles triangle definition.

CAT and ABT are right angles by the tangent theorem.  

Thus, CAB and CBA are both 90 - 65 = 25.

ACB is 130 because triangles' angles add up to 180.

APB is one half of ACB by the inscribed angles theorem.

The measure of the arc APB will be 230°. Then the correct option is D.

What is a circle?

It is the circle of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

We know that the tangents are equal.

Then triangle ΔATB is an isosceles triangle.

Then the angle ∠TAB and angle ∠TBA are congruent.

We know that the angle sum of a triangle is 180°.

∠TAB + ∠TBA + ∠ATB = 180°

               65° + 65° + z = 180°

                                  z = 50°

We know that the radius and tangent of circle make 90°.

And the angle sum of quadrilateral is 360°.

∠TAC + ∠TBC + ∠ATB + ∠ACB = 360°

                   90° + 90° + 50° + y = 180°

                                                y = 130°

Then the measure of the arc APB will be

x = 360° – 130°

x = 230°

The measure of the arc APB will be 230°.

Then the correct option is D.

Explanation:

If we had x^2+2x + ___, then 1 must go in the blank so that we have x^2+2x+1 = (x+1)^2

So we must add 1 to both sides to complete the square for the x terms. To find this value '1' we take half of the x coefficient 2 to get 1, then square it to get 1^2 = 1.

We have

x^2+y^2 + 2x - 20y - 20 = 0

x^2+y^2 + 2x - 20y - 20 + 1 = 0 + 1

(x^2+2x+1) + y^2 - 20y - 20 = 1

(x^2+2x+1) + y^2 - 20y = 1 + 20

(x+1)^2 + y^2 - 20y = 21

After completing the square for the x terms. Repeat for the y terms. Take half of -20 to get -10, which squares to 100. Add this to both sides

(x+1)^2 + y^2 - 20y = 21

(x+1)^2 + y^2 - 20y + 100 = 21+100

(x+1)^2 + (y - 10)^2 = 121

The equation is in the form (x-h)^2 + (y-k)^2 = r^2 where

The center is (h, k) = (-1, 10). The radius is r = 11.

n^3 + 2n -2.

Answer:

Step-by-step explanation:

We have to add the like terms. Like terms are with variables of same power.

-8n³ and 7n³  are like terms , now add the coefficient of n³ , -8 + 7 = -1

-8n³ + 7n³ = -1n³

(-8n³ + 4n - 8) + (7n³ - 2n + 6 )

Combine like terms

= -8n³ + 7n³    + 4n - 2n  - 8 + 6

= -1n³ + 2n - 2

Answer: The maximum value is 35.94

Step-by-step explanation:

We have the function:

f(x) = -16*x^2 + 34*x + 20

This is a quadratic equation, and the first thing we can see is that the leading coefficient is smaller than zero, which means that the "arms" of the graph will go downwards, which means that the maximum of our function will be at the vertex.

First, we know that the vertex of a quadratic function is when f'(x) = 0.

f'(x) = 2*(-16*x) + 34 = 0.

x = -34/(-2*16) = 34/32 = 17/16.

Now we evaluate our function in the point x = 17/16.

f(17/16) = -16*(17/16)^2 + 32*(17/16) + 20 = 35.94

The maximum value is 35.94

Using the vertex, it is found that the maximum value of the function is of 36.

The function is given by:

[tex]f(x) = -16x^2 + 32x + 20[/tex]

Which is a quadratic function with coefficients [tex]a = -16, b = 32, c = 20[/tex].

The maximum value of a quadratic function with [tex]a < 0[/tex] is at the vertex, in which the value is:

[tex]f_{MAX} = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}[/tex]

Hence, in this problem:

[tex]f_{MAX} = -\frac{(32)^2 - 4(-16)(20)}{4(-16)} = 36[/tex]

The maximum value of the function is of 36.

The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].

Step-by-step explanation:

The equation for the area of a triangle ([tex]A_{\bigtriangleup}[/tex]) is:

[tex]A_{\bigtriangleup} = \frac{1}{2}\cdot b \cdot h[/tex]

Where:

[tex]b[/tex] - Base, dimensionless.

[tex]h[/tex] - Height, dimensionless.

The expression for each triangle are described below:

First Triangle ([tex]b = 3\cdot x + 7[/tex], [tex]h = 5\cdot x - 1[/tex])

[tex]A_{\bigtriangleup,1} = \frac{1}{2}\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]

Second Triangle ([tex]b = 3\cdot (3\cdot x+7)[/tex], [tex]h = 2\cdot (5\cdot x -1)[/tex])

[tex]A_{\bigtriangleup,2} = 3\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]

The difference between the area of the original triangle and the area of the new triangle is:

[tex]\Delta A_{\bigtriangleup} = A_{\bigtriangleup,2}-A_{\bigtriangleup,1}[/tex]

[tex]\Delta A_{\bigtriangleup} = 3\cdot (3\cdot x+7)\cdot (5\cdot x-1)-\frac{1}{2} \cdot (3\cdot x+7)\cdot (5\cdot x-1)[/tex]

[tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex]

The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].

Answer:

[tex]T_{12} = 354294 + 354294i[/tex]

Step-by-step explanation:

Given

Geometric Sequence (GP)

[tex]T_1 = 2 + 2i[/tex]

[tex]r = 3[/tex]

Required

Determine T₁₂

The nth term of a GP is calculated as thus;

[tex]T_n = ar^{n-1}[/tex]

In this case;

[tex]n = 12[/tex];  [tex]r = 3[/tex] and [tex]a = T_1 = 2 + 2i[/tex]

Substitute these values in the above formula

[tex]T_{12} = (2 + 2i) * 3^{12-1}[/tex]

[tex]T_{12} = (2 + 2i) * 3^{11}[/tex]

[tex]T_{12} = (2 + 2i) * 177147[/tex]

Open the bracket

[tex]T_{12} = 177147 * 2 + 177147 * 2i[/tex]

[tex]T_{12} = 354294 + 354294i[/tex]

Hence, the 12th term of the sequence is [tex]T_{12} = 354294 + 354294i[/tex]
