Question

If the equation 18^2 + b^2 = 30^2 is found to be true, what do we know about the triangle?
A. The triangle is a right triangle with a missing side of 34.99.
B. The triangle is a right triangle, and the legs are 30 and 24.
C. The triangle is a right triangle, and the hypotenuse is 18.
D. The triangle is a right triangle with a missing leg length of 24.

Answer 1

Compute b: b^2 = 30^2 − 18^2 = 900 − 324 = 576, so b = 24. Thus the triangle is right with the missing leg 24. Answer: D.
