Use Pythagoras' theorem to find the length of the wire:- 202+142 = 596 and the square root of this is the length of the wire which is about 24.4 feet

If you look up at something and it is at 45 degrees then the distance away from the base is equal to its height. You are 50 feet from the pole.
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
The height of the pole is 19.62ft
A 90-degree angle is a right angle.

Height of telephone pole: 20*tan(70) = 55 feet rounded
That depends on the angle of elevation which has not been given.
