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
he tower is 39°. Find the height of the tower.
1 answer:
Answer:
20.9 feet
Step-by-step explanation:
<em>The figure attached below can be formed through the information given.</em>
<u>Step 1: Find angle y</u>
<em>All angles of a triangle are equal to 180°</em>
<em>67 + 39 + y = 180</em>
<em>y = 74°</em>
<u>Step 2: Use sin formula to find H</u>
<em>a/sin a = b/sin b</em>
<em>32/sin 74 = b/sin 39</em>
b = 20.9 feet.
The height of the tower is 20.9 feet.
