A20-foot ladder touches a building 16 feet up the wall. what is the measure of the angle the ladder makes with the ground (macb)?

Choice A) 53 degrees

======================================================

Check out the attached image. Notice how I'm only focusing on the triangle. I have erased any other extra lines or unneeded info. We have the opposite side 16 and the hypotenuse 20. We'll use the sine ratio and the arcsine function as well. On your calculator, the arcsine function is "arcsin" or it might be labeled "sin^(-1)"

Let x = measure of angle ACB

sine = opposite/hypotenuse

sin(angle ACB) = (height)/(length of ladder)

sin(x) = 16/20

sin(x) = 4/5

sin(x) = 0.8

x = arcsin(0.8)

x = 53.130102354156

x = 53 when rounded to the nearest whole number

So that's why angle ACB is roughly 53 degrees

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
