1. If each angle in a pentagon is the same measure, what is that measure?

36°
540°
180°
108°

The answer is 108 because all pentagons have to add up to 540, and all pentagons have 5 sides so 540 divided by 5=108

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.
