Answer:
X is zero.
Explanation:
I just got into geometry this year, but I can help you. Unfortunately, I am unfamiliar with any postulates, theorems, and everything else. I will just be using simple terms to explain what I am doing.
Here is the information we are given: the measure of angle QCD is x + 95, the measure of angle BCD is 2x + 118, and the measure of angle BCQ is 23°. We know that if we add the measure of angle BCQ and the measure of angle QCD, we will get the measure of angle BCD. We are already given the measure of angle BCQ. Therefore, we can make the algebraic equation:
Now, we need to solve for x.
Therefore, x is zero. We can check our answer by plugging in x to our original equation:
Does 118 equal 118? Yes, it does. X is zero.
