What’s the rest of your question???
If I read it right then 1. -147
2. -100
The equation for this is a^2+b^2=c^2 so your equation would be 7^2+20^2=X
So you square the 7 and the 20 then take the square root of X and you get
X=21.19
:)
The answer is a because u replace x with zero to find the why value
please rate this XD
