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>
<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.
