Answer:
Linear pair is a pair of adjacent angles formed when two lines intersect.
so,
and
are linear pairs.
Linear pairs are always supplementary.
therefore,
......[1]
Also, it is given in figure, 
Substitute in [1], we get;
Simplify:

Exterior- Angle sum Property states that if the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle.
then by Exterior angle sum property ;

Substitute the values given in the figure;

simplify;

therefore, the measure of angle ACB is, 
He is wrong, it is 38000
38496, the 8 is the thousand spot
round the number after it up or down
4 rounds down and 9&6 go down with it
38,000
Answer:
22
Step-by-step explanation:

We first have to come up with an equation that satisfies this. The equation is y+11=7.
Then we subtract 11 from both sides. y+11-11=7-11.
Then we get the answer y=-4.
I'm pretty sure your right. the answer is mantle.
