A guy wire makes a 67° angle with the ground. Walking out 32 feet further from the tower, the angle of elevation to the top of t

kirill [66]

Answer:

20.9 feet

Step-by-step explanation:

The figure attached below can be formed through the information given.

Step 1: Find angle y

All angles of a triangle are equal to 180°

67 + 39 + y = 180

y = 74°

Step 2: Use sin formula to find H

a/sin a = b/sin b

32/sin 74 = b/sin 39

b = 20.9 feet.

The height of the tower is 20.9 feet.
