Question

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

Answer 1

Answer: 7.5

Step-by-step explanation:

use pythagorean theorem

13^2 + b^2 = 15^2

- 13^2

b^2 = 56 - square root

= 7.5

Answer 2

Answer:

Consider:

$hypotenuse = 15$

$leg1=13$

$leg2 = x$

$a^2+13^2=15^2\\a^2+169=225\\a^2=56\\a=\sqrt{56} \\a=7.483$
