In my sketch I see a non-rightangled triangle with angles
42° , 110° and 28°
with the side opposite the 42° as the guy wire
by the sine law:
x/sin42 = 25/sin28
x = 25sin42/sin28
= .....
A guy wire attached to the top of an electric pole makes a 70deg angle with the level ground. At a point 25 feet from the guy wire (farther away from the pole), the angel of elevation to the top of the pole is 42deg. How long is the guy wire?
