Answer:

Since the ratio of the angles is 7:2:1, we can write the angles as 7x, 2x, and x, for some x. Since the sum of the angles in a triangles is 180, we have 7x + 2x + x = 180. Combining the x's on the left-hand side, we have 10x = 180. Finally, dividing by 10 gives x = 18.

Answer:

17.) 12

18.) 1/15

Step-by-step explanation:

2 ÷ $\frac{1}{6}$

This problem is asking how many $\frac{1}{6}$ 's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be $\frac{1}{6}$ of the whole. Divide the other box into 6 parts as well, and you will get 12 of these $\frac{1}{6}$ parts. Check your answer by multiplying 12 by $\frac{1}{6}$ . The answer is $\frac{12}{6}$ which is also equal to 2.

$\frac{1}{3}$ ÷ 5

For this one, think of it as we have one big box divided into thirds. We want to divide each $\frac{1}{3}$ portion by 5. So you should have 5 tiny boxes in each $\frac{1}{3}$ which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is $\frac{1}{15}$ . Check your answer by multiplying $\frac{1}{15}$ by 5 and you get $\frac{5}{15}$ which is equal to $\frac{1}{3}$ .
