Question

Find the value of the variable in the triangle below. Round decimal answers to the nearest tenth.

Answer 1

Consider:

`hypotenuse = 15`

`leg1=13`

`leg2 = x`

`a^2+13^2=15^2\\a^2+169=225\\a^2=56\\a=√(56) \\a=7.483`

Answer 2

Answer: 7.5

Explanation:

use pythagorean theorem

13^2 + b^2 = 15^2

- 13^2

b^2 = 56 - square root

= 7.5
