I believe it's around 50 miles.
Answer:
A. 64 cubic meters
B. 62 cubic meters
C. 78 cubic meters
D. 58 cubic meters
Step-by-step explanation:
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90°
in this problem
(x+21)+<span>(2x+21)=90-------> 3x+42=90-------> 3x=48-----> x=16</span>°
