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

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.

its 9 my doods

Step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
