Answer:

y=15

Step-by-step explanation:

Because of the exterior angle theorem angle A plus angle b or equal to 146.

so you set 5y+3+4y+8=146 and solve

5y+3+4y+8=146

9y+11=146

9y=135

y=15

Answer:

  • Option C is correct.

Step-by-step explanation:

  • 5y + 3 + 4y + 8 + (180 - 146) = 180
  • => 9y + 11 + 34 = 180
  • => 9y + 45 = 180
  • => 9y = 180 - 45
  • => 9y = 135
  • => y = 135 ÷ 9
  • => y = 15

Conclusion:

Hence, Option C is correct.

Hoped this helped.
