A 48 meter antenna mast is stabilized by a 52 meter guy wire How far from the base of the mast is the guy wire secured to the ground A 20m B 50m C 60m D 100m

A)  20m

Step-by-step explanation:

52^2 - 48^2 = b^2

√2704 - √ 2304 =  √400

b^2 =  √400 =  20

As this is Pythagoras as we do not have any 2nd angle measure.

if it was trigonometry we could use 90  degree as part of the sum

48/ sin(?)x90 = 52

Then try other angle by deducting angle shown from 90

m/sin (?) x 90 = 52 etc.

But to guarantee you would find the base you could use tan.

250-112 = 138
