Answer:
m3 is 60 degrees
Step-by-step explanation:
Angles 1 & 3 are complementary angles. What that means is that the two angles equal 180 degrees. We already have 120 degrees with m1, so subtract that from 180 for 60 degrees.

Step-by-step explanation:
1). ![\frac{6}{9}=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B9%7D%3D%5Cfrac%7B2%7D%7B3%7D)
= 2 : 3
2). 6 : 4 = ![\frac{6}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B4%7D)
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
6 : 4 = 3 : 2
3). ![\frac{15}{45}=\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B45%7D%3D%5Cfrac%7B1%7D%7B3%7D)
= 1 : 3
4). 12 : 8 = ![\frac{12}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B8%7D)
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
= 3 : 2
And
= 3:2
Therefore, 12 : 8 = ![\frac{18}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B12%7D)
5). ![\frac{21}{12}=\frac{7}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B12%7D%3D%5Cfrac%7B7%7D%7B4%7D)
= 7 : 4
6). 4 : 10 = ![\frac{4}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D)
= ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
Therefore, equivalent ratios are,
a). 2 : 3 = ![\frac{6}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B9%7D)
b). 3 : 2 = 6 to 4
c).
= 1 : 3
d). 18 to 12 = 12 to 8
e). ![7:4=\frac{21}{12}](https://tex.z-dn.net/?f=7%3A4%3D%5Cfrac%7B21%7D%7B12%7D)
f). ![\frac{2}{5}=4:10](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%3D4%3A10)
