Step-by-step explanation:
There are no green counters in the bag.
The equation we can use to find the value of x in the diagram given is: B. (5x + 30) + 5x = 90.
<h3>What are Complementary Angles?</h3>
Angles that give a sum of 90 degrees when added are referred to as complementary angles.
The angles, (5x + 30) and 5x are complementary angles, since the sum of both gives a right angle (90 degrees).
Therefore, the equation that we can use to find x in the diagram is: B. (5x + 30) + 5x = 90.
