Question

in the figure two straight lines AB and CD intersect at O.if COT =60 degrees find a,b,c​

Answer 1

<AOC=<DOB(vertically opposite angle)

CD is a line

60°+b+4b=180°

60°+5b=180°

5b=180°-60°

5b=120°

b=24°

again CD is a line

60°+24°+a=180°

84°+a=180°

a=180°-84°

a= 96°

AB is a line

96°+2c=180°

2c=180°-96°

2c=84°
