Answer 1

Find the measure of value of AB for m∠P

There are two parts to this question.

First, determine the length of the radius of the arc of her sight lines.
If you draw it out,
sin(34/2)=r/(16+r)
where r is the radius of the monument

Then,
Tan(34/2)=r/R
where R is the radius of the arc.

Then multiply
R*(34*pi/180)=the measure

I get 12.824 m
using pi=3.14

I will not solve your equation, but this is how you perform it.
