The figure is a triangle.

what is the first step of indirectly proving this statement?

assume the figure does not have three sides.

assume the figure is a triangle.

assume the figure is not a triangle.

assume the figure has three sides.

Assume the figure has three sides.

(a figure with three sides is always a triangle)

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.

You just divide and you will find x
