11 and 9 are coefficient

Because they both have a variable to them.

So first we find the angle C first

Since A-C-D is a straight line, then its 180 degree

With that we can do 113-180 = 67

So angle C is 67 degree

Now as a general rule, the total of all angles in a triangle is equal to 180

So to find for angle B we can write an algebraic equation

Angle A + Angle C + Angle B = 180

Let x represent Angle B

So

72 + 65 + x = 180

we now solved for x

X was solved to be 43 then the measure of Angle B is 43 degree

**Answer:**

About 66% (Choice B)

**Answer:**

No solutions for n

**Step-by-step explanation:**

Distribute the 4 to the -8 and the 2n

-4 + 4*-8 + 4*2n = -37 + 8n

Multiply

-4 - 32 + 8n = -37 + 8n

Subtract 8n on both sides

-4 - 32 = -37

Subtract on the left

-36 = -37

No solutions because -36 does not equal -37
