Answer:

$\huge \boxed{a$

Step-by-step explanation:

Subtract by 2 both sides of equation.

$\displaystyle a+2-2$

Simplify, to find the answer.

$-10-2=-12$

$\displaystyle a$ , which is our answer.

Answer:

a < -12

Step-by-step explanation:

Isolate the variable, a. Treat the < as a equal sign, what you do to one side, you do to the other. Subtract 2 from both sides:

a + 2 < -10

a + 2 (-2) < -10 (-2)

Simplify:

a < -10 - 2

a < -12

a < -12 is your answer.

Answer: 130

In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130

**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles
