Answer:
135
Step-by-step explanation:
This is a 8 sided figure. All of the interior angle measurements are the same. The sum of the interior angles can be found
by (8-2)(180) = 1080
or 180(8) - 360 = 1080 Both formulas give you the same answer.
= 135 All of the angles are equal. Take the total and divide it among the 8 angles.
She must start out going 8 miles per hour until the time elapsed is 1 hour at which time she drops 1.5 miles per hour. The same happens again in the second hour and the third.
The graph must have hours on the x axis and speed on the y axis.
The starting point is (0,8)
The graph must be
y = 8 - 1.5x
You need three points.

0 8
1 6.5
2 5
Answer:
Therefore the value of x is 15.
Step-by-step explanation:
Given:
AD || BC
m∠ B = (9x + 15)°
m∠ A = (3x - 15)°
To Find:
x = ?
Solution:
AD || BC ...............Given
If two lines are parallel and sum of the interior angles are supplementary.
i.e m∠ B and m∠ A are interior between Parallel lines.
∴
Substituting the given values we get
∴
Therefore the value of x is 15.
