Question

What is the length of BC in the right triangle below?

Answer 1

C. 39

Explanation:

Use Pythagorean Theorem to find the missing length

15² + 36² = C² Simplify

225 + 1296 = C² Add

1521 = C² Take the square root of both sides

39 = C

Answer 2

Hey there! :)

Answer:

C. BC = 39 units.

Explanation:

Use the Pythagorean theorem to solve for BC. Let BC = c, AB = a, and AC = b.

c² = a² + b²

c² = 15² + 36²

Square and simplify:

c² = 225 + 1296

c² = 1521

c = √1521

c = 39 units.

Therefore:

BC = 39 units.
