Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66
Answer:
The answer to your question is: the last option
Step-by-step explanation:
m² - 6m + 6m -36
Simplify like terms m² - 36
Factor (difference of squares) (m + 6) (m - 6)
Answer: 75 degrees on the other two angles because all of the angles added together should be 180. So if you do 180-30 then divide that by 2 you get the other two angles.

Answer: 24 square units
Step-by-step explanation:
It appears the shaded area of the rectangle is half of the rectangle's area. This means if we find the area of the rectangle and divide it by 2 we will know the area of the shaded portion.
The formula for the area of a rectangle is 
Where
l is the length (8 for this)
w is the width (6 for this)
A is the area
However, since we are finding half the area we will divide lw by 2
Sub the values into the formula
