Lines ab and cd (if present in the picture) are straight lines. find x. give reasons to justify your solutions.

If line AB and CD are parallel to each other, hence the value of x from the given diagram is 39.2

To find the value of x from the given diagram, we will have to use the formula for finding the angle at a point.

152 + 3x + x + x + 12 = 360

152 + 12 + 5x = 360

164 + 5x = 360

5x = 360 -164

5x = 196

x = 196/5

x = 39.2

Hence the value of x from the given diagram is 39.2

x = 28°

Step-by-step explanation:

∠AOD and ∠BOC are vertical angles, hence congruent. That means the sum of ∠COE, ∠EOF, and ∠FOB is ∠BOC.

... 3x +x +(x+12°) = 152°

... 5x = 140° . . . . collect terms, subtract 12°

... x = 28° . . . . . . divide by 5

what i would say the best answer is a. 40.5
