Hello!

As you can see, the angle is a straight angle, which measures 180°. One angle measures 80°.

180 - 80 = 100

That means the rest added all together measure 100°.

3x + 2x = 5x

5x = 100

Divide both sides by 5

$\frac{5x}{5} = \frac{100}{5}$

$\framebox{x = 20 \°}$

Tell whether each statement is a proportion:

erma4kov [3.2K]

Answer:

1. Yes

2. No

3. No

4. No

5. Yes

Step-by-step explanation:

Do you mean equal proportion?

1. 3 : 9 = 6 : 18 TRUE because 3 : 9 = 1 : 3 and 6 : 18 = 1 : 3

2. 28 : 7 = 64 : 16 FALSE because they are just not related.

3. 95 : 100 = 17 : 20 FALSE because the closest they get are 19 : 20 ≠ 17 : 20

4. 60 : 80 = 14 : 16 FALSE because the closest they get are 60 : 80 = 6 : 8 and 14 : 16 = 7 : 8

5. 200 : 300 = 24 : 36 TRUE because 200 : 300 = 2 : 3 and 24 : 36 = 2 : 3
