Question

In a 51-inch television, the length of the screen's diagonal is 51 inches. If the screen's height is 25 inches,

what is the width? Round your answer to the nearest tenth of an inch.

Answer 1

The width is 44.5in.

Explanation:

25^2 + b^2 = 51^2

625 + b^2 =2601

b^2= 2601-625=1976

Square root it (1976)

=44.45= 44.5

Answer 2

44.452

Explanation:

Using the Pythagorean theorem you can use:

51^2 = 25^2 + w^2

2601 = 625 +w^2

w^2 = 1976

w = 44.452
