Question

If in a right triangle one of the legs measures 15 cm and the hypotenuse measures 20 cm. How much does the other leg measure? help!!!

Answer 1

Using Pythagoras theorem we can find the other leg measure..
A^2 + B^2= H^2
15^2+ B^2 = 20^2
225+B^2= 400
B^2= 400-225
= 175
B= square of 175
=13.2
Therefore the other leg’s measure is 13.2cm

Answer 2

Answer:

The other leg would measure $\sqrt{175}$

Step-by-step explanation:

I got the answer by squaring 20 and 15 and got 400cm and 225cm. Then I subtracted 400 by 225 and got 175. Then since 175 is not a perfect square you would leave it as $\sqrt{175}$.

I hope this helps!!
