A. 145°
B. 90°
C. 45°
D. 35°


Answer:
A. 145°
Explanation:
To find angle C you subtract 180-145. This is 35°. Next, the angles in a triangle add up to 180 degrees, so subtract 180-35. This is 145°. You don't need to find the exact values of A and B because the answer requires them added together, so 145 is the answer.
