Question

42. If the figure AB is a straight line, then the valuer of a+bis​

Answer 1

Answer:

Since AB is a straight line, the sum of all the angles on AB at a point O is 180o.

∴(3x+7)o+(2x−19)o+x=180o     (Linear angles)

⇒6x−12=180⇒6x=192⇒x=32o

So, ∠AOC=(3x+7)o=(3×32+7)o=103o,

∠COD=(2x−19)o=(2×32−19)o=45o,∠BOD=32o
