Answer:

a = 52 -- READ EXPLANATION, YOU WON'T BE PREPARED FOR A TEST WITHOUT IT.

Step-by-step explanation:

We know 2a + 24 is on one side of a diameter line, along with <a

to find out what it is,  we can do the equation (2a + 24) + a = 180

this would simplify as 3a + 24 = 180

180 - 24 = 156

156 / 3 = 52

so we now know that a = 52

How do I find the missing value
liberstina [14]
Okay. Since the "y" value and 82* are on the same straight line, their values will always add up to make a sum of 180. So if you subtract 82 from 180 you get 98*. So your "y" value is equal to 98*.

Now, all of the degree values added together should give you a sum of 360, so now we must add the values we know, in order to find the "x" value. So, 112*+82*+98*=292. Now we know that the difference of 360 and 292 will give us the x value. So finally, 360-292=68. So your "x" value is equal to 68.

y=98
x=68
