He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps
Answer:
by <u>AAS</u>
Step-by-step explanation:
According to the following two triangles, 
and 
are congruent by <u>Angle-Angle-Side</u> (AAS), because there are two angles shown and share a side, which is in the middle between triangles.
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
