Answer:

3. x = 8

4. x = 80

Step-by-step explanation:

3. 37 and (6x - 11) are congruent angles:

37 = 6x - 11

48 = 6x

x = 8

4. 2(x - 9) and 142 are congruent angles:

2(x - 9) = 142

2x - 18 = 142

2x = 160

x = 80

Answer:

  • x = 8, x = 10

Step-by-step explanation:

Q3

Corresponding angles are congruent

  • 6x - 11 = 37
  • 6x = 11 + 37
  • 6x = 48
  • x = 8

Q4

Angle2 is complementary with 142 and alternate interior with  2(x + 9)

  • 142 + 2(x + 9) = 180
  • 142 + 2x + 18 = 180
  • 2x + 160 = 180
  • 2x = 20
  • x = 10
