20, 0.05 is the center of the circle
Answer:
110 degrees
Step-by-step explanation:
since every triangles degrees add up to 180 all you have to do is find 1 and 3. since the 4 is 150 degrees and the line always has to add up to 180 3 is 30 degrees. then we add 2 and 3 which gets us 70. then 180 - 70 which is 110 so 3 is 110.

Answer:
A, C and D
Step-by-step explanation:
Given
![\frac{3}{5}a + 10](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Da%20%2B%2010)
Required
Select 3 equivalent expressions
![\frac{3}{5}a + 10](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Da%20%2B%2010)
Express 3 as 2 + 1
![\frac{2 + 1}{5}a + 10](https://tex.z-dn.net/?f=%5Cfrac%7B2%20%2B%201%7D%7B5%7Da%20%2B%2010)
Rewrite as:
![\frac{2a + a}{5} + 10](https://tex.z-dn.net/?f=%5Cfrac%7B2a%20%2B%20a%7D%7B5%7D%20%2B%2010)
Split
----- Option (A)
![\frac{3}{5}a + 10](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Da%20%2B%2010)
Express 10 as 14 - 4
![\frac{3}{5}a + 14 - 4](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Da%20%2B%2014%20-%204)
Rewrite as:
--- Option (C)
![\frac{3}{5}a + 10](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7Da%20%2B%2010)
Factor out 1/5
--- Option D
