Question

use the Pythagorean theorem to find the length of hypotenuse​

Answer 1

Answer:

The Answer is 58.

Step-by-step explanation:

Let ABC a right angled triangle in which length of AB = 7 cm and AC = 3 cm.

We have to find the length of BC.

Solution : By Pythagoras Theorem,

= BC² = AB² + AC²

= BC² = 7² + 3²

= BC² = 49 + 9

= BC = 58

Here, BC = x = 58

Answer 2

Answer:

First, you need to find which is your A and B sides and plug those numbers in. this should give you a^2 + b^2 = x^2

This problem's answer:

7^2 + 3^2 = x^2

7 x 7 = 49

3 x 3 = 9

49 + 9 = x

58 = x

Remember to get the square root of your answer ^ first

The square root of 58 is ~7.616.

Therefore, your answer is 7.616
