1. 28^2+21^2=c^2,\(c=35.\)

2. 6^2+7^2=c^2, c^2=85, \(c=\sqrt{85}.\)

3. \(c^2+(\sqrt{3})^2=(2\sqrt{3})^2, c^2=9, c=3.\)

Ok, all of these are relativaly simple.

The formula you will be working with for all of these is a^2+b^2=c^2

Im not going to give you the answers only explain how to do it.

#1. 28 and 21 are a and b. Insert them into the formula to get 28^2+21^2=c^2

Solve for 28^2+21^2 and get 1225

now you are at 1225=c^2

Your answer will be the square root of 1225.

#2. In this problem 6 and 7 are a and b.

Put them in the equation above to get 36+49=c^2

Your answer for this will be the square root of 85

#3. In this problem 2 times the square root of 3 is c and the square root of 3 is a.

Put them into the equation above to get the square root of 3 squared (3) + b^2=2times the square root of 3 squared (2 times the square root of 3.

This gets us to the Square root of 3+ b^2=2 times the square root of 3

Minus Square root of 3 from right side to get b^2 equals the square root of three. so b equals the square root of the square root of three

Have A nice day!
