Based on the side lengths given (a, b, and c), which triangles are right triangles?

to determine if a triangle is a right triangle, use the pythagorean theorem

a^2 +b^2 = c^2

if this is true is it a right triangle

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
