Step-by-step explanation:
Solution:
<u>Note that:</u>
- 6x + 26 = 92 (Vertically opposite angle)
- 92 + 92 + z + z = 360
<u>Finding x.</u>
- 6x + 26 = 92
- => 6x = 92 - 26
- => 6x = 66
- => x = 11
<u>Finding z.</u>
- 92 + 92 + z + z = 360
- => 184 + 2z = 360
- => 2z = 360 - 184
- => 2z = 176
- => z = 176/2 = 88
