Question

In a right triangle, find the length of the side not given, if a=8 and b=15

Answer 1

a² + b² = c²
(8)² + (15)² = c²
64 + 225 = c²
289 = c²
17 = c

Answer 2

to find the length of a missing side of a right triangle you have to use the Pythagorean theorem. so 8*8=64 15*15=225 so to find side c you add the two answers 225+64 and the answer is and find the square root which is 17. Hope this helps
