A*a + b*b = c*c
9*9 + 12*12 = c*c
81 + 144 = c*c
225 = c*c
✓225 = 15
c = 15
The hypotenuse is 15.

I am assuming you mean hypotenuse of a right triangle with sides 12 and 9

using the pythagorean theorem

a^2 +b^2 =c^2 where a and b are the sides and c is the hypotenuse

12^2 +9^2 = c^2

144 +81 = c^2

225 = c^2

c=15

The hypotenuse is 15 mi

I need help with this proof, the given and prove are at the top. Plzzzz help
Goshia [24]

Answer:  The proof is mentioned below.

Step-by-step explanation:

Here, Given : m∠AOC = 160°  m∠AOD= (3x-10)° and  m∠ DOC= (x+14)°

Prove: x= 39°

      Statement                                              Reason

1. m∠AOC = 160°, m∠AOD= (3x-10)°    1.  Given

and m∠ DOC= (x+14)°    

2. m∠AOD+m∠DOC=m∠AOC         2. Because OD divides ∠AOC

                                                              into ∠AOD and ∠DOC

3. (3x-10)° +(x+14)°= 160°                     3. By substitution

4.  4x+4 = 160°                                    4. By equating like terms

5. 4x= 156°                                          5. By subtraction property

                                                             of equality

6. x= 39°                                              6. By division property of equality
