Question

which of the following shows the length of the third side in inches of the triangle below

Answer 1

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let x be the length of the third side, then

73² = 48² + x²

5329 = 2304 + x² ( subtract 2304 from both sides )

3025 = x² ( take the square root of both sides )

x = $\sqrt{3025}$ = 55 → C
