Question

The TV screen is 52 in. wide and 29 in. high. How do you find the length of of its diagonal?

Answer 1

`c approx59.54`

Explanation:

For this we use the Pythagorean theorem: `a^2+b^2=c^2`, where `a` and `b` are the two shorter sides and `c` is the diagonal one. Using this, we get:
`29^2+52^2=c^2`
`c^2=3545`
`c approx59.54`
