Question

The length of the hypotenuse of a right triangle is 145 units. The length of one leg of the triangle is 144 units. Mike wrote the following step to find the length of the unknown leg: Length of the unknown leg = 1452 − 1442 = 21,025 − 20,736 = 289 units Which statement best explains whether Mike's step is correct or incorrect?
PLEASE HELP I WILL GIVE BRAINLIEST


A- It is incorrect because the length of the unknown sides is the square root of 289.

B- It is incorrect because the length of the unknown side is the square root of 41,761

C-It is correct because the length of the unknown side is the difference of the lengths of the sides

D- It is correct because the length of the unknown side is the difference of the squares of the side

Answer 1

Answer:

A

Step-by-step explanation:

a^2 + 144^2 = 145^2

a^2 + 20736 = 21025

a^2 = 289

a = sqrt(289)
