If two angles are supplementary and one angle measures 65°, what should be the measure of the other angle?
other angle equals to 115°.
Answer:
B. -3
Explanation:
Our equation is: . We see that both sides have a term with denominator ax - 2, so let's add
to both sides:
Now multiply both sides by ax - 2:
We essentially want to make the terms on each side match. Look at the coefficient of x² on the left side: it's 24. That means on the right side, it should be 24, as well. Then, set -8a equal to 24:
-8a = 24
a = -3
Thus, the answer is B.
