Question

I need help this is 8th-grade math it is due tomorrow and the term ends on Friday

Answer 1

the missing side length = 12m

Explanation:

use the pythagorean theorem--a^2 + b^2 = c^2

a^2 + b^2 = c^2

a^2 + 5^2 = 13^2

a^2 + 25 = 169

- 25 -25

a^2 = 144 -- square each side

a = 12

Answer 2

5^2+x^2=13^2 25+x^2=169 169-25=144 x=12 twelve is your answer btw
