Question

Solve the Pythagorean theorem for a, assuming a, b, and c are positive. a^2+b^2=c^2

A. a=c^2+b^2


B. a=c+b


C. a=√c^2-b^2


D. a=c-b

Answer 1

B. A=c+b is the answer

Answer 2

it should be c because the puthagorean theorem is c^2=a^2+b^2 so subtract b^2 to the other side to keep a by itself and then sqare root both sides to get ride of the square on the a
