If the diagonal of a television screen Is 20 Inches and the width is 12 inches,
1 answer:
Answer:
c. 56 in.
Step-by-step explanation:
use pythagorean theorem ( ) where a, b, and c are the lengths of the side of a right triangle. c is the length of the longest side across from the right angle of the triangle (the diagonal). To find the length of the TV a=
. Now that you have the length you simply must add the length of each side of the TV. Perimeter = sum of the lengths of every side. TV has 4 sides length is 16 and width is 12. So, 16 + 16 + 12 + 12 = 56 in

Height of the triangle is the altitude of the triangle and which is drawn perpendicular from the vertex of the triangle to the opposite side. The height of the tringle is 24 units. Hence option 2 is the correct option.
<h3>Given information-</h3>The triangle for the given problem is shown in the image below.
Form the figure the length of the each side is units.
As all the sides are equal thus the is a equilateral triangle in which the height of the divides the triangle into two equal part of the length
at point <em>R.</em>
Height of the triangle is the altitude of the triangle and which is drawn perpendicular from the vertex of the triangle to the opposite side.
Now in the , the length of the hypotenuse is
units and the length of the base is
units. Let <em>h </em>is the height of the triangle thus by the Pythagoras theorem,
Solve for <em>h,</em>
