Answer: angle AOB = 40 degrees
====================================================
Explanation:
The smaller angles AOB and BOC combine to the largest angle AOC
By the angle addition postulate, we can say,
(angleAOB) + (angleBOC) = (angleAOC)
(3x+4) + (8x-28) = 108
11x-24 = 108
11x = 108+24 .... adding 24 to both sides
11x = 132
x = 132/11 .... dividing both sides by 11
x = 12
We can use this x value to find each angle
angle AOB = 3x+4 = 3*12+4 = 40 degrees
angle BOC = 8x-28 = 8*12-28 = 68 degrees
As a check,
(angleAOB)+(angleBOC) = (40)+(68) = 108
which matches with the measure of angle AOC. This confirms our answers.

The value of WZ in the given similar polygons, is 72
What are similar polygons?
When polygons are similar their corresponding angles are congruent and their corresponding sides are proportional.
Given that, quadrilateral ABCD and quadrilateral WXYZ are similar,
The order of the proportionality statement tells us which angles and sides are corresponding.
To solve, set up a proportion.
AD/WZ = DC/ZY
12/WZ = 6/36
Cross multiply.
6(WZ) = 12x36
6(WZ) = 432
Divide both sides by 6
WZ = 72
Hence, the value of WZ is 72
