1.	11.In the given figure, two straight lines AB and CD intersect at O. If LCOT60Â°, find a,b,c,2c4b60Â°
Answer» Since ab and cd are straight lines, 4b+b+60 = 180° 5b = 180-60 5b = 120 b = 24° Also, 4b+2c = 180° 2c = 180-424 2c = 180-96 2c = 84 c = 42° Also, 2c+a = 180° a = 180-242 a = 180-96 a = 84° Like my answer if you find it useful!

Answer»

Since ab and cd are straight lines,

4b+b+60 = 180°

5b = 180-60

5b = 120

b = 24°

Also, 4b+2c = 180°

2c = 180-4*24

2c = 180-96

2c = 84

c = 42°

Also, 2c+a = 180°

a = 180-2*42

a = 180-96

a = 84°
