Answer:

The answer is 12

Step-by-step explanation:

First, you do 2+8=10. You do that first becuase it is in the parentheses

After that, You do 15+3=18

Then, 4 and the 2 over it. Which is a exponent. And that tells you to multiple the number by itself. So 4x4=16.

But it also says subtract the 4. So now you Add the 10+18=28

Then you subtract 16 from 28. 28-16=12.

Thats how you get your answer.

Answer:

Step-by-step explanation:

The sum of the three angles of any triangle is equal to 180 degrees.

180-58=122

122/2=61

We divide by two because we are missing the other two angles but they are both equal.
