Answer:

(a) The width is 40 inches

(b) It will not

Step-by-step explanation:

Given

D = 50 -- Diagonal

Solving (a): H = 30 --- (height).

Find the width (W)

To do this, we make use of Pythagoras theorem

D^2 = H^2 + W^2

This gives:

50^2 = 30^2 + W^2

2500 = 900 + W^2

Collect Like Terms

W^2 = 2500 - 900

W^2 = 1600

Take square roots

W = 40

Solving (b): Will it fit into a 30 in wide cabinet?

In (a) above, we calculated the width of the TV to be 40 inches

This implies that, the width is greater than the width of the cabinet.

<em>So, it will not fit in</em>
