A telephone is anchored to the ground by a long cable called a guy wire, at a point 5 meters from the base of the pole, the wire makes an angle of 72.5 degrees with the horizontal. What is the length of the guy wire?

HELP ASAP! I forgot how to compute for this (Pythagorean Theorem) D:

  • Math -

    We don't need Pythagorus, we need trig.

    let the height be h

    h/5 = tan 72.5°
    h = 5tan 72.5 = appr 15.858 m
