7.5 inches

Answer 1

Given: A larger triangle has a base of 10 inches and height of 6 inches.

To find: The height of the reduced triangle?

Solution:

• Now we have given a triangle which has a base of 10 inches and height of 6 inches.
• Another triangle is given but it is not to the scale.
• We have provided that a reduction of a triangle by using a scale factor of 0.8, means a new triangle has sides reduced by the factor of 0.8

• So:

            the height is 6 inches of original triangle.

            The height of new triangle will be:

            6 x 0.8 = 4.8 inches

Answer:

            So the height of the reduced triangle is 4.8 inches.
