Question

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

Answer 1

D) 39

Explanation:

Since this is a right triangle, we can use the Pythagorean thm formula

Formula: a² + b² = c²

15² + 36² = c²

225 + 1296 = c²

1521 = c²

`√(1521) =√(c^2)`

c = 39

Answer 2

D. 39

Explanation:

BC^2 = BA^2 + AC^2

BC^2 = 15^2 + 36^2

BC = square root (1521)

BC = 39
