The 2 interior angles add to the exterior angle
26+13=x
39=x
x=39°
because
remember, all angles add to 180
26+13+BCA=180
39+BCA=180
minus 39 both sides
BCA=141
look, we want x
BC is a striaign line which is 180
BCA+x=180
141+x=180
minus 141 from both sides
x=39°
<span>Commutative postulate for addition is Illustrated for the real numbers 3 + 2 = 2 + 3. Commutative Law of Additi): If a and b are in N, then a + b = b + a. An operation is commutative if you can change the order of the numbers involved without changing the result. Addition and multiplication are both commutative</span>

Answer:
x = 3
Step-by-step explanation:
5(2 - x) = 7x - 26
Distribute;
10 - 5x = 7x - 26
Add 5x to both sides;
10 = 12x - 26
Add 26 to both sides;
36 = 12x
Divide both sides by 12;
x = 3
