You guys don’t have to tell me the answer just explain how to solve

Okay. The formula to the Pythagorean theorem is a^2+b^2=c^2
In this specific problem you have to find B so you will plug into the formula what you know and you will solve it.
24+b=40
You see, now it’s a one stepped equation, you will now subtract 24 from 40 which will give you B!
And B is 16!
I hope this helps!

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
