Question

Find the value of x. Round your answer to the nearest tenth.

Answer 1

4.0

Explanation:

In a 30-60-90 right triangle, the ratio of the lengths of the sides is

short leg : long leg : hypotenuse

1 : √3 : 2

7 is the long leg.

x is the short leg.

1/√3 = x/7

x√3 = 7

x = 7/√3

x = 4.0
