Answer:
Your answer would be 180 I think.
Step-by-step explanation:
Let the measure of one of the supplementary angles be .
Measure of the other angle is times .
So, measure of the other angle is .
If the sum of the measures of two angles is , then the angles are supplementary.
So,
3 a = 180 °
To isolate , divide both sides of the equation by .
3 a 3 = 180 ° 3 a = 60 °

m < 1 = 180 - 90 - 78
= 180 - 168
= 12 degrees
Area= 19.63 units squared Circumference= 15.71 units
Area= π r ^2
Circumference= 2π r
Answer by JKismyhusbandbae: Radius is 12 and perimeter is six times this, i.e. 72.
Cube surface area:
A= 9126 m^2
4+(25-512)=-487+5=-482
