Angle ACD and angle CAD are angles that add to 90 degrees (60+30 = 90) and they are non-adjacent. They do not share a common vertex. So this is why the two angles fit the description for number 12.

In contrast, two adjacent complementary angles are angle FDG and angle GDE. They add to 90 degrees and share the common vertex point D. They also share a common segment DG.

crimeas [40]

The distribution of the balls is an illustration of proportions, and 4 of the golf balls are yellow

<h3>How to determine the number of yellow golf balls?</h3>

The distribution of the balls are given as:

Total = 28

Yellow = 1/7

The number of yellow balls is given as:

Yellow = 1/7 * Total

This gives

Yellow = 1/7 * 28

Evaluate the product

Yellow = 4

Hence, 4 of the golf balls are yellow
