Answer:
The distance between the end of the ramp and the bottom of the platform is about 9.8 feet
Step-by-step explanation:
use the pythagorean theorem (a²+b²=c²) to solve
a and b are the legs, c is the hypotenuse
plug in given values:
2² + x² = 10²
solve for x:
x² + 4 = 100
x² = 96
x ≈ 9.80
Answer:
<CFE = 28
<RPQ = 53
Step-by-step explanation:
1)
<CFE + 152 = 180
<CFE = 180 - 152
<CFE = 28
2)
Complementary means the angles add up to 90 so:
<RPQ + 37 = 90
<RPQ = 90 - 37
<RPQ = 53
