The diagonal measure of a rectangular T. V screen is 42 inches. The width of the screen is 36.6 inches

What is the height of the screen? Round to the nearest tenth.

A^2 + b^2 = c^2

The diagonal is the hypotenuse (c).

36.6^2 + b^2 = 42^2

1339.56 + b^2 = 1764

Subtract 1339.56 from both sides.

b^2 = 425.44

Square root both sides.

b = 20.6 inches

A^2 + b^2 = c^2

The diagonal is the hypotenuse (c).

36.6^2 + b^2 = 42^2

1339.56 + b^2 = 1764

Subtract 1339.56 from both sides.

b^2 = 425.44

Square root both sides.

b = 20.6 inches
