Solutions

S1. Ans.(c) 
Sol. ∠AOC=∠AOB-∠COB=68°-42°=26° 

S2. Ans.(c)
Sol. ∠XOZ=∠XOY+∠YOZ=56°+34°=90° 

S3. Ans.(c)
Sol. Let angles be 8x and x
8x + x = 180 
x = 20° then angles are 160° and 20°  

S4. Ans.(d)
Sol. 58° + 42° + z = 180°
z = 180° – 100 = 80°
1/2 z=40° 

S5. Ans.(c)
Sol. x + y + 2 × 50° = 360° 
x + y = 360° – 100° = 260°  

S6. Ans.(c)
Sol. ∠POC=1/2∠AOC 
∠COQ=1/2∠COB 
∠POC+∠COQ=1/2 (∠AOC+∠COB) 
∠POQ = 1/2 (180°) 
∠POQ=90° 

S7. Ans.(c) 
Sol. Alternate angle

S8. Ans.(a)
Sol. ∠COD=20° 
∠OCD=60° 
 ∠ODC=180°-(20°+60°) 
= 100°

S9. Ans.(c)
Sol. y = 180° – 103° = 77°
x + y + 35° = 180° 
x = 180° – 35 – 77 = 68° 

S10. Ans.(b)
Sol. ∠PRS=69°+25°=94°
