Question

PLEASE HELP!!!

Answer 1

Hello,


to find other side ; 

a = √ hypo^2- leg^2
so, a = √19^2-12^2

therefore it is 14.7 

Hope this helps.

Answer 2

Pythagorean theorum- a²+ b² = c²
C² is always the hypotenuse, and the two legs are a² and b².
When you plug the numbers in, you get 12²+b²=19²
Simplify: 144+b²2=361
b²=361-144
b²=217
b=√217
b=14.7
