First you find the area of the square which is 8²=64 than you find the area of a circle using the formula πr² you get 201.06 and divide it by 4 because you only need the quarter and you get 50.26 the last step is to add the two areas together and you get 64+50.26=114.2

The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. find the measure o
saul85 [17]
 2 angle A and B are Complementary means that the sum of their measures is 90°. 

 2 angle A and B are Supplementary means that the sum of their measures is 180°. 


Thus, if the measure of angle A is x:

the measure of the supplement is 180°-x
the measure of the complement is 90°-x


"The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. "

let the measure of the angle be x, then we have:

180°-x=40°+2(90°-x)

180°-x=40°+180°-2x

2x-x=40°

x=40°


Answer: 40°

We have 26.8 meters per second so whats 26.8 meters in kilometers? there is 0.0268 kilometers in 26.8 meters. So now we need to multiply 0.0268 by 3,600 to get 96.48


So your answer would be 96.48 km/h
