Answer:
7.6
Step-by-step explanation:
This is the Pythagorean Theorem. In order to solve this, you must use the equation a squared + b squared = c squared. Remember that across from the right angle is c, which matters the most. When you plug it in, you should have 3 squared plus 7 squared = c squared.
3 squared is 9.
7 squared is 49.
Now you should have 9 + 49 = c squared.
49 + 9 = 58.
Now you should have 58 = c squared.
Then you find the square root of 58.
The square root of 58 is 7.61577310586.
When you round this, you should have 7.6
The side c = 7.6
