Consider this right triangle with given measures.
A triangle has side lengths 12 centimeters and b. The hypotenuse is 15 centimeters.
What is the unknown leg length?

Pythagorean theorem:a2+b2=c2

122+b2 = 152

144 + b2 = 225

b2 + 81

b = cm

Respuesta :

Answer:

9

Step-by-step explanation:

So, we have 144+b^2=225.

That means b^2=81

To get rid of the squared part of b^2, we square root both sides.

This gets you b= + or - 9, but since there's no negative side length, it's positive 9.
