8 0
(99+85+74+x)/4=83
multiply both by 4
99+85+74+x= 332
258+x=332
subtract 258 both sides
x= 74

He must get a 74.

To check answer:
99+85+74+74= 332
332/4 = 83

It’s right!

Hope it helps

Use the diagram to find the height of statue.round to the nearest tenth
jeyben [28]

Answer:

7.3 ft

Step-by-step explanation:

The information given represents a right angle triangle with the following:

reference angle = 52°

Adjacent side length = 5.7 ft.

Opposite side length = height of the statue = h

Applying the trigonometric ratio formula, we would have:

tan(52) = \frac{h}{5.7}

Multiply both sides by 5.7

tan(52) \times 5.7 = \frac{h}{5.7} \times 5.7

tan(52) \times 5.7 = h

h = 7.3 ft (nearest tenth)
