Ples The diagram represents a reduction of a triangle by using a scale factor of 0.8.

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

What is the height of the reduced triangle?
4.0 inches
4.8 inches
5.2 inches
7.5 inches

Step-by-step explanation:

The reduction factor of 0.8 means the lengths in the reduced triangle are 0.8 times those of the original.

Then the original 6 inch length is reduced to 0.8×6 inches = 4.8 inches in the reduced triangle.

I think it's 4.8 inches :/

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
