Traingles C and D are similar. The area of triangle Cis 47.6in2. The base of triangle D is 6.72in. Each dimension of D is 6/5 the corresponding dimension of C. What is the height of D?
How in the world do you this problem!!
Please help BIG TEST TOMMOROW!!! :)

First, calcuate the base of triangle C, wouldn't it be 5/6 of 6.72in? Now, the altitude of C must be the area/base.
Now, the altitude of D must be 6/5 of the altitude of C.
Neat.
