Question

Solve for X in the triangle.
Answer choices
√89
√39
√26

Answer 1

A

Explanation:

a^2 + b^2 = c^2

25 + 64 = c^2

c^2 = 89

c = sqrt(89)

Answer 2

√89

Explanation:

This is a right triangle, so we can use Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 +8^2 = x^2

25+64 = x^2

89 = x^2

Take the square root of each side

sqrt(89) = sqrt(x^2)

sqrt(89) =x
