2. If DEF is an isosceles triangle with DE = EF , find x and the measure of each side.
8x-13 5x+17 x+21

The answer is

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The answer is a. yes, it asks a question that can be answered correctly (by measuring hands).
