Question

the leaning tower of pisa in italy makes an angle of 86 degrees with the ground. a person standing on the ground approximately 82 feet from the tower at an angle of 69 degrees. how tall is the tower?

Answer 1

Explanation:

C. 181 ft

A. 139 ft

B. Lighthouse A is closer to the boat since lighthouse B is 80.2 meters away

C. Either 46.27 miles or 17.43 miles

C. 88 Degrees

B. About 109 meters

Answer 2

see the picture to better understand the problem

we know that
in the triangle ABC
∠A+∠B+∠C=180°
∠C=180-(86+69)-----> ∠C=25°
Applying the law of sines
b/sin B=c/sin C------> b=c*sin B/sin C-----> b=82*sin 69/sin 25
b=181.14 ft

the answer is
181.14 ft
