Line ob bisects angle nod and line oa and line oc trisects angle nod and angle aob is 20 degrees less than angle noa. find the measure of angle nod and boc

Step-by-step explanation:

If lines OA and OC trisect angle NOD, then

By angle addition postulate:

If line OB bisects ange NOD, then

Angle AOB is 20 degrees less than angle NOA, then

By angle addition postulate,

Thus,

and

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
