Question

Suppose ABC  is a right triangle with C = 90°. If a = 6 and b = 8, find c .
A)c = 9
B)c  = 18
C)c  = 10
D)c  = 15
E)c  = 6

Quizplus · Accepted Answer

Using the Pythagorean Theorem, we have:
c^2 = a^2 + b^2
c^2 = 6^2 + 8^2
c^2 = 36 + 64
c^2 = 100
c = sqrt(100)
c = 10. Therefore, the answer is choice C.
