Question

Helppp!
So, the question is "Find the missing length of the right triangle." The hypotenuse is 12 and leg ( i think ) is 7. I used the formula "a squared + b squared = c squared" and got 193.

My choices are
a) 5
b) 19
c) the square root of 97
d) the square root of 193

I have already taken the quiz once and it told me that d is wrong.
Am I doing something wrong?

Answer 1

the pythagoras's theorem is ths..

(hypt)2=(base)2+(perp)2
so in your case it will become.

(base)^2=(hypt)^2-(perp)^2

now plug in vales and get result..

here perp=leg

Answer 2

Thank you!!
