Answer:

b. 2692 ft

Step-by-step explanation:

The relation of interest between the sides of the right triangle is ...

Tan = Opposite/Adjacent

Using the given numbers, that is ...

tan(32°) = (building height)/(4300 ft)

Multiplying by 4300 ft, we get ...

building height = (4300 ft)·tan(32°) ≈ 2686.9 ft

This is the height above the observer's eyes, so the height of the building above the ground is ...

2687 +5 = 2692 . . . . feet

The building is 2692 feet tall.

PLS ESTIMATE/ 67% of 8.7

Studentka2010 [4]

67 percent of 8.7

$\frac{67}{100} \times \frac{x}{8.7}$
$100x = 67 \times 8.7$

$100x = 582.9$

Divide by 100 on both sides to isolate the x

$x = 5.829$
Round up (to the nearest tenth place and whole number)

$x = 6$
$x = 5.8$
