The solution is: the value of the angles a, b and c are : a = 60, b = 90, c = 100.
Here,
We have that in line CHF, it has two given and one unknown angle.
The total angle of one straight line is 180.
Given that:
a = 180 - 50 -70 = 60
The angle intersecting the CHFD line can be computed by the the total angle inside the triangle.
Angle on EFH would give 180-40-60 = 80 and on EFD the angle would be 100 from 180-80.
Since angle C is congruent to the angle EFD.
c = 100
Take note that in a 4 sided polygon (GEFH), the total exterior angle is 360 degrees.
The different angle would be
angle GHF = 50 + a = 50+60 = 110
angle EFH = 80
angle FEG = 180- c = 180-100 = 80
ANGLE EGH = 360 - GHF -EFH -FEG = 360 - 110-80-80 = 90
since angle AG is congruent to EGH, we can calculate for the angle b which is congruent to its opposite. This would give us formula of
360 = (90+90) + (b) +(b)
360 = 180 +2b
b = 90
Hence, The solution is: the value of the angles a, b and c are : a = 60, b = 90, c = 100.

Find an equation of the line with the slope m=−1/8 that passes through the point (−5,0). Write the equation in the form Ax+By=C.
Answers
Answer:
x+8y= -5
Step-by-step explanation:
1) the required equation of the line has an slope-interception form:
y=mx+i, where m - slope, i - interception.
2) if the given point belongs to the required line, then it is possible to substitute its coordinates into the equation, then:
0=m*(-5)+i; ⇔-5m+i=0;
3) if the slope m= -1/8, then
-5*(-1/8)+i=0, ⇒5/8+i=0; ⇒ i= -5/8.
4) finally, the required equation is (m= -1/8; i= -5/8):
y= (-1/8)*x-5/8; ⇔ x+8y= -5.

The complete sentence is 6 x 4 =( 3 x 4) + (3 x 4)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
6 x 4 =( x 4) + (3 x 4)
Now, split 6 as two equal quantities
6 = 3+ 3
So, 6 x 4 =24
( 3x 4) + (3 x 4)
= 12+ 12
= 24
Hence, LHS = RHS.

Hi!
So, first, let's just form the equation:
We know that all the side lengths equal 12 cm.
So the equation will be:
5 + 3 + x = 12
The answer you put in the box is:
5 + 3 + x
To find the value of x, we just solve this equation:
5 + 3 + x = 12
Combine like terms:
8 + x = 12
Same to both sides:
x = 12 - 8
x = 4

The second derivative of the function f is given by f" (x) = sin(x^2/8)-2 cos x. The function f has
many critical points, two of which are at x = 0 and x= 6.949. Which of the following statements is
true?
Answers
The answer choice which is true about the function f as described in the task content is; Choice D; f has a local maximum at x=0 and at x=6.949.
Which answer choice represents a true statement about function f?Since the equation which represents the second derivative of the function f is given; we have that;
By evaluating f'' (x) at each of the given values of x; we have that;
f'' (0) = sin ( 0² / 8 ) - 2 cos (0) = 0 - 2 (1) = -2
f'' (6.949) = sin ( 6.949² / 8 ) - 2 cos (6.949)
f'' (6.949) = -1.880.
On this note; since -1.880 < 0 and also, -2 < 0; it follows that the function f has a local maximum at x = 0 and x = 6.949.
Complete question includes answer choices;
a) f has a local minimum at x=0 and at x=6.949.
b) f has a local minimum at x=0 and a local maximum at x=6.949.
c) f has a local maximum at x=0 and a local minimum at x=6.949.
