Question

If ru is an altitude of rst find rs

Answer 1

Answer:

The correct answer is Option D. 20

Step-by-step explanation:

From the figure we get,

<RUS = 90° because RU ⊥ TS

To find the value of x

It is given that <RUS = 4x + 54

Therefore we can write,

4x + 54 = 90

4x = 90 - 54 = 36

x = 36/4 = 9

To find RS

It is given that,

RS = 3x - 7 = 3*9 -7 = 20

Therefore the correct option is Option D . 20
