D. Should be the correct answer
Answer:
one unique solution x=1 y=4
36/-9-5=14/7-11
36/-9=-4
-4-5=-9
14/7=2
2-11=-9
The measure of the interior angle at vertex C is D. 144.
<h3>How to calculate the angle?</h3>
Based on the information given, the angle will be calculated thus:
8x + 8x + 8x + 3x + 3x = (5 - 2) × 180
30x = 540
Divide both side by 30
30x/30 = 540/30
x = 18
Therefore, at vertex C, we have 8x. This will be:
= 8x
= 8 × 18
= 144
