Mei is standing next to a statue in the park. If Mei is 5 feet tall, her shadow is 3 feet long, and the statues shadow is 10 1/2
alisha [4.7K]
The problem presented above is an example in which we can use the concept of ratio and proportion. The ratio between the heights of Mei and the statue should be the same to the ratio of their shadows. Letting x be the height of the statue. 
                                  5 ft/ x ft = 3 ft / 10.5 ft
The value of x from the equation above is 17.5 ft.

PLEASE HELP WITH THESE TWO QUESTIONSSS 1. Which value is equivalent to sin20∘?
Nata [24]

Answer:

a) \cos(70\degree)

b) 12.72 units

Step-by-step explanation:

Recall that the sine and cosine are completed functions.

This means that:  \sin(x)=\cos(90-x)

\sin(20\degree)=\cos(90-20)

\sin(20\degree)=\cos(70\degree)

Recall that: sine ratio is opposite/hypotenuse

\sin 58=\frac{|PQ|}{15}

This implies that:

|PQ|=15\sin 58

|PQ|=15(0.848)

|PQ|=12.72
