Answer:

w=67°

Step-by-step explanation:

First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°

Answer:

  • 43°

Step-by-step explanation:

We observe on the picture that:

  • (12x + 11)° and  47°  are  vertical angles and vertical angles are equal as per definition
  • Angle w° is complementary angle with (12x + 11)° and complementary angles add to 90° as per definition

Therefore

  • w = 90°- (12x + 11)°
  • w = 90° - 47°
  • w = 43°
