Question

In a figure ray AD stands on the line CB , angle BAD=(2x+10)d and angle CAD =(5x + 30)d find the value of x and also write angle BAD and angle CAD

Answer 1

The angles BAD and CAD form a linear pair, which means that the sum of these angles is 180 degree. 
So, by framing an equation, we get
(2x+10)+(5x+30)=180
Solve for x. 
2x+10+5x+30=180
7x+40=180
7x=180-40
7x=140
x=140/7
x=20
Hence, value of x is 20. 
Angle BAD=2*20+10 = 40+10 = 50
Angle CAD=5*20+30 = 100+30 = 130. 
I hope it helps.
