Answer:
Step-by-step explanation:
We know that:
- y - 9 + x + 1 = 180
- z + 3 + 112 = 180
- y - 9 + z + 3 = 180
- x + 1 + 112 = 180
- y - 9 = 112
- x + 1 = z + 3
- y - 9 + x + 1 + z + 3 + 112 = 360
Solution of x:
- x + 1 + 112 = 180
- => x + 113 = 180
- => x = 180 - 113
- => x = 67
Solution of y:
- => y - 9 + x + 1 = 180
- => y - 9 + 67 + 1 = 180
- => y + 59 = 180
- => y = 180 - 59
- => y = 121
Solution of z:
- => x + 1 = z + 3
- => 67 + 1 = z + 3
- => 68 = z + 3
- => z = 68 - 3
- => z = 65
Hence, the answers are:
Check:
- y - 9 + x + 1 + z + 3 + 112 = 360
- => 121 - 9 + 67 + 1 + 65 + 3 + 112 = 360
- => 360 = 360
Hence, the answers are proved as correct.
Hoped this helped.
