in given figure 2 straight lines AB and CD intersect at O . if angle COT = 60 , find a , b ,c
Answers
Given : in Fig two straight lines AB and CD intersect at O ∠COT = 60°
To find : a , b & c
Solution:
AB is a straight line
Hence
4b + 60° + b = 180°
=> 5b = 120°
=> b = 24°
CD is a straight line
60° + b + a = 180°
=> b + a = 120°
=> 24° + a = 120°
=> a = 96°
4b + 2c = 180°
=> 4(24) + 2c = 180°
=> 96° + 2c = 180°
=> 2c = 84°
=> c = 42°
a = 96° , b = 24° , c = 42°

Answer:
a=96°, b=24°, c=42°
Step-by-step explanation:
AB is a straight line
4b+60°+b=180
5b=120°
b=24°
CD is a straight line
60°+b+a=120°
a=96°
4b+2c=180°
4(24)+2c=180°
2c=84°
