Answer:
x = 65
y = 64
Step-by-step explanation:
We can see that the two angles with y will make up a total of 180 degrees. So, we can start by adding 12. (adding 16, but subtracting 4) That gives us 192. We can then divide by 3, the number of times y is in the angles.
192 / 3 = y
192 / 3 = 64
y = 64
Now, we have to solve the blank angle in the middle. We know that (2y + 4) is going to be 132, so the blank angle is 48.
Now, we can use that to solve for x. The triangle interior angle sums will add up to 180, so we start by subtracting the known angles from the triangle.
180 - 67 = 113
113 - 48 = 65
x = 65
I hope this helps :)
