Question

The length of the third side.

Answer 1

7.6

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

(Hope this answers your question).

Answer 2

7.61577

Explanation:

This is because 3x3+7x7= 58 and square root of 59 gives answer
