Answer:

14

Step-by-step explanation:

2 (x+4) = 3(x-2)

(distribute)

2*x + 2*4 = 3*x + 3 * -2

2x + 8 = 3x + -6

     +6          +6 (add 6 on both sides)

2x + 14 = 3x

-2x          -2x (subtract 2x on both sides)

14 = x

x is 14, we have found x.

Answer:

  ∠A = 44°

Step-by-step explanation:

In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.

Happily, that relation is "the sum of angles in a triangle is 180°." This means ...

  84° +(x +59)° +(x +51)° = 180°

  (2x + 194)° = 180° . . . collect terms

  2x = -14 . . . . . . . . . . divide by °, and subtract 194

  x = -7 . . . . . . . . . . . .divide by 2

Now, the measure of angle A is ...

  ∠A = (x +51)° = (-7 +51)°

  ∠A = 44°
