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

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:
Consider:
[tex]hypotenuse = 15[/tex]
[tex]leg1=13[/tex]
[tex]leg2 = x[/tex]
[tex]a^2+13^2=15^2\\a^2+169=225\\a^2=56\\a=\sqrt{56} \\a=7.483[/tex]
