Question

A TV screen has a diagonal length of 156cm, the angle in the top corner is 37◦. Calculate the height of the TV screen

Answer 1

The TV screen is an illustration of a right triangle

The height of the TV screen is 124.6 cm

How to calculate the height

The diagonal is given as:

d = 156 cm

The angle at the top is given as:

Angle = 37 degrees

The height is then calculated using the following cosine ratio

$\cos(37) = \frac h{156}$

Make h the subject

$h = 156 * \cos(37)$

Evaluate

h = 124.6

Hence, the height of the TV screen is 124.6 cm
