Awire is attached to the top of a 45-foot telephone pole and anchored to the ground. the angle of elevation is 64 degrees. how long is the wire to the nearest foot?

Length of wire = 50 ft

Step-by-step explanation:

In the figure below AB is the telephone pole and C is the point on the ground where wire is anchored.

so we have

AB= 45 ft

∠ACB= 64°

Let is assume the length of the wire be x ft

now in Δ ABC

we can plug AB= 45, ∠C= 64°and AC=x

so we have

°

°

now we have sin 64°=0.8988

ft

rounding to nearest foot

x= 50 ft

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
