  x = 50

Step-by-step explanation:

Vertical angles have equal measures.

  2(x +10)° = (3x -30)°

  2x +20 = 3x -30 . . . . . . divide by ° and eliminate parentheses

  50 = x . . . . . . . . . . . . . add 30-2x to both sides

Check

The top angle is 2(50 +10)° = 120°.

The bottom angle is (3(50) -30)° = 120°. The angles are congruent, as they should be.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
