Answer: x = 7
Step-by-step explanation:
x(x-1) = 42 (Area)
By trial and error method let's take x = 7
We get
7(7-1) = 42
7 x 6 = 42
42 = 42
Therefore LHS = RHS
Therefore it's 7

<u>Given</u>:
The two angles A and B are vertical angles.
The measure of ∠A is x and the measure of ∠B is 5x - 20.
We need to determine the measure of ∠A.
<u>Value of x:</u>
Since, the angles A and B are vertical angles and the vertical angles are always congruent.
Thus, we have;
Substituting the values, we have;
Adding both sides of the equation by 80, we have;
Thus, the value of x is 20.
<u>Measure of ∠A:</u>
The measure of ∠A can be determined by substituting x = 20 in the measure of angle A.
Thus, we get;
Thus, the measure of ∠A is 20°
