E)82

Step-by-step explanation:

The formula is

A^2 + B^2= C^2

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

Answer 2

Answer:

E

Step-by-step 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 = $\sqrt{6724}$ = 82 → E
