153.8 = 3.14r^2

Divide each side by 3.14 to get r alone.

48.9 = r^2

Take the square root of each side to isolate r.

r = 6.999

r= 7

Find the size of an angle which is five times its supplement ​
zavuch27 [327]

Two supplementary angles when addd together equal 180.


let one angle = x

The second angle is 5 times that so would be 5x


x + 5x = 180

Simplify:

6x = 180

Divide both sides by 6:

X = 30

One angle is 30, the second angle would be 150


The answer is 150

HELPPPPP MEEEEE!!! #7

Angle 6 and Angle 7 are each 90° since they’re on a straight line and are both equal.
180-90= 90
*you subtract from 180 because that’s how many degrees are in a straight line*
Angle 7 and Angle 1 are alternate exterior angles so that makes them congruent by definition.
