Answer:

m∠1 = 130°

m∠2 = 158°

Step-by-step explanation:

For the given figure, we have;

The measure of angle m∠1 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;

m∠1 = 99° + 31° = 130°

m∠1 = 130°

Similarly, the measure of angle m∠2 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;

m∠2 = 28° + m∠1 = 28° + 130° = 158°

m∠2 = 158°.

Answer:

Step-by-step explanation:

Given lines:

These have same slopes of 2/3 and therefore are parallel, so no intersection. There is no solution if lines don't intersect.

The graph is attached as well to show lines are parallel.

Answer:

x = m × p - n

Step-by-step explanation:

[tex]m = n + \frac{x}{p} [/tex]

We can first multiply both sides by p.

[tex]m \times p = n + x[/tex]

And now we only have n left with x, so we subtract n on both sides.

[tex]m \times p - n = x \\or \\ x = m \times p - n[/tex]

Answer:

6n-14

Step-by-step explanation:

First, put 6 times a number down, which is 6n, then minus 14, so it would be 6n-14.

The numerical form of statement 4 is less than 6 times a number, and n is

6n - 4.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

The given statement is 4 less than 6 times a number, n.

Therefore, The statement can be numerically expressed as,

6×n - 4.

= 6n - 4.

If 6n - 4 is an expression then 6n - 4 = 0  is an equation.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Answer:

x ≈ 2.76

Step-by-step explanation:

The inscribed angle (34x + 4) is half the measure of its intercepted arc, then

34x + 4 = [tex]\frac{1}{2}[/tex] × 196° = 98 ( subtract 4 from both sides )

34x = 94 ( divide both sides by 34 )

x ≈ 2.76 ( to the nearest hundredth )

Answer:

Pythagoras's theorem

Step-by-step explanation:

In the given drawing, there are three right triangles (two smaller triangles formed inside one right triangle), which are;

1) The smallest right triangle with side lengths 'b', 'f', and 'd'

2) The intermediate right triangle with side lengths 'f', 'a' and 'c - d'

3) The right triangle ΔABC containing the other two with side lengths, 'a', 'b', 'c'

By trigonometric ratio we have;

1/cos(B) = a/(c - d) = c/a

By cross multiplication, we get

a² = c² - c·d

Similarly, we have;

The vertex angle for the small right triangle at C = ∠B

1/sin(B) = b/d = c/b

∴ b² = c·d

Therefore, adding the values of 'a²', and 'b²' together, we get;

a² + b² = c² - c·d + c·d = c²

Therefore;

a² + b² = c² which is Pythagoras's theorem.

Step-by-step explanation:

The probability of all correct is [tex]\frac{1}{4}[/tex] or 25%.

Given that,

According to the situation, calculation of given data are as follows,

Probability of all correct = [tex]\frac{a}{(a \times b )}[/tex]

By putting the value, we get,

Probability = [tex]\frac{3}{(3 \times 4) }[/tex]

= [tex]\frac{3}{12}[/tex]
