Question 218124
A 20 in (on the diagonal) TV has a width of 16 in. What is the height?


Using Pythagorean formula, {{{a^2 + b^2 = c^2}}} to find the height, and using H for height, we get: {{{H^2 + 16^2 = 20^2}}}


{{{H^2 + 256 = 400}}}


{{{H^2 = 400 - 256}}}


{{{sqrt(H^2) = sqrt(144)}}}


Therefore, H or height = {{{highlight_green(12)}}}
