I need help with this question

Answer 1

15.7 inches

Explanation:

We can use the Pythagorean Theorem a² +b² = c² to solve for the remaining leg of the triangle

In the image attached, we will be solving for "b" in which this case I denoted as x

So manipulating our equation to solve for b we get
`b=\sqrt{c^(2)-a^(2) }`

Plugging in the respective values we get
`x = \sqrt{(27)^(2)-(22)^(2) } =√(729-484)=√(245) = 7√(5)`

Our height of the TV is
`7√(5)` which is ≈15.7 inches
