Question

What is the diagonal length at a TV
screen whose chinensione
are 80x60cm?​

Answer 1

Answer:

$a {}^{2} + b {}^{2} = c {}^{2} \: pythagorean \: theorem$

${80}^{2} + {60}^{2} = c {}^{2}$

$6400 + 3600 = {c}^{2}$

$10000 = {c}^{2}$

$c = \sqrt{10000}$

Therefore c = 100

Hence, the diagonal length at a TV

screen whose dimension are 80x60cm is 100.
