Find the missing side of the triangle. Round your answers to the nearest tenth if necessary. 9 ft

2.5 ft

9.4 ft

7.5 ft

Given:

In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.

To find:

The value of x.

Solution:

Pythagoras theorem: In a right angle triangle,

Using Pythagoras theorem, we get

Taking square root on both sides, we get

The measure of missing side is 7.5 ft. Therefore, the correct option is D.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
