Question

Find the value of side A on the right triangle, given that side B = 12 cm and side C = 15 cm. A) 3 cm B) 9 cm C) 25 cm D) 27 cm

Answer 1

Answer:B=9

Explanation:

9 cm. It is a right triangle so you must use the Pythagorean Theorem to find the missing side: a2+ b2 = c2. You would have a2 + 122 = 152. So a2 + 144 = 225 where you subtract 144 from each side to get a2 = 81. Then you take the square root of both sides to get a = 9.

Answer 2

the answer is B) 9cm
