I had to do this and it’s fake, my whole class got it wrong even though we all put the right answer so ya
4 +5 = 9 and 12 + 3 =15 and there is more than this
hope I helped
So you can set up proportion.

Here, you need to solve for C.
You can do that by multiple both sides by 360 and then you should get

Hope this helps.
Answer:
a = 38⁰
b = 54⁰
c = 54⁰
Step-by-step explanation:
a + 142⁰ = 180⁰ because a straight line = 180⁰
b + 38⁰ + 88⁰ = 180⁰ because the angles of a triangle equal 180⁰, and the missing measurement = 38⁰ because it is a vertical angle to angle a
c + 88⁰ = 142⁰ because the angles are corresponding angles
