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

<h3><u>Answer:</u></h3>
  • Option C is correct.
<h3><u>Step-by-step explanation:</u></h3>
  • 5y + 3 + 4y + 8 + (180 - 146) = 180
  • => 9y + 11 + 34 = 180
  • => 9y + 45 = 180
  • => 9y = 180 - 45
  • => 9y = 135
  • => y = 135 ÷ 9
  • => y = 15
<h3><u>Conclusion:</u></h3>

Hence, Option C is correct.

Answer:

see explanation

Step-by-step explanation:

Multiply both sides by 9 to eliminate the fraction

9K = 5(F + 459.67) ← divide both sides by 5

F + 459.67 = \frac{9}{5} K ( subtract 459.67 from both sides )

F = \frac{9}{5}K - 459.67
