Question

AOB is a straight lin. find the value of X hence find angle AOC and angle BOD​

Answer 1

Answer:

the angle between a to b is linear line so it is creating 180 degree

Step-by-step explanation:

it has given that one angle at top in 55 degree so lets find r + 20 angle

180 -55 = 125

x+20 = 125

x= 125 - 20

x = 105

now lets find 3x - 5

other side will also be 125 degree because the angle of congruent so

3x - 5 = 125

3x = 125 - 5 = 120

x = 120/3 = 40

hope it help you
