Answer: C
Step-by-step explanation:
We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.
The correct answer is C.
2x+57+61=180
2x+118=180
2x=62
X=31
5x-12 would be equivalent to that expression
8.25/3 = $2.75 per ice cream
2.75 * 2 = $5.50
It would cost $5.50 for 2 ice cream
