Using the side lengths determine whether the triangle is acute obtuse or right.

Either acute or right i’m sorry if it’s not that helpful i wish you the best tho stay safe

Ithink the answer is last one.

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.
