Answer 1

75 inches is the answer.

Answer 2

Hello!

You can use this by using the Pythagorean theorem


`a^(2) + b^(2) = c^(2)`

c is the hypotenuse which is the angle opposite the right angle

a and b are the other two sides

you put the values in that you know


`72^(2) + b^(2) = 78^(2)`

square the numbers

5184 +
`b^(2)` = 6084

Subtract 5184 from both sides


`b^(2)` = 900

Take the square root of 900

square root of 900 = 30

The answer is 30

Hope this helps!
