Question

I need help with this it’s geometry Pythagorean theorem

Answer 1

E

Explanation:

Since the triangle is right use Pythagoras' theorem to solve for BC

The square on the hypotenuse (BC) is equal to the sum of the squares on the other 2 sides, that is

BC² = 80² + 18² = 6400 + 324 = 6724 ( take the square root of both sides )

BC =
`√(6724)` = 82 → E

Answer 2

E)82

Explanation:

The formula is

A^2 + B^2= C^2

the two sides that make up the right angle is always A and B
