Call x and y those angles. If they are complementary, then their sum equals 90°:
x + y = 90°
y = 90° - x
The ratio of them is 5 to 1. So,
x/y = 5/1
x/(90° - x) = 5/1
x = 5 * (90° - x)
x = 450° - 5x
x + 5x = 450°
6x = 450°
x = 450°/6
x = 75°
The measure of the other angle is
y = 90° - 75°
y = 15°
The angles are 75° and 15°.
I hope it helps. =)
Step-by-step explanation:
Given
Radius (r) = 4 inches
height (h) = 11 inches
Total surface area of cylindrical oil can is
= 2πr ( r + h)
= 2 * 22 / 7 * 4 ( 4 + 11)
= 2 * 22/7 * 4 * 15
= 377.14 inches ²
