Answer:

  • x = 86°

Step-by-step explanation:

We know that:

  • Triangle = 180°

Let's use the triangle property to solve for x.

Work:

  • 74 + 20 + x = 180
  • => 94 + x = 180
  • => x = 180 - 94
  • => x = 86

Hence, the value of x is 86°

180= 20+74+x
180= (20+74)+x
180= 94+x
180-94= x
86=x
