Question

Please help! I only have 4 questions left!!!

Which set of angle measures could be the measures of the interior angles of a triangle?
A) 60°, 45°, and 70°
B) 30°, 85°, and 25°
C) 55°, 90°, and 35°
D) 110°, 15°, and 45°

Answer 1

C because the angle needs to add up to 180 degrees

Answer 2

Go through the list of choices. Add up the angles. If the result is 180, then we have the answer

A) 60+45+70 = 175, which isn't 180 so we scratch this off the list

B) 30+85+25 = 140, also doesn't work

C) 55+90+35 = 180, we found the answer

D) 110+15+45 = 170, doesn't work

------------------------

In summary, the answer is choice C) 55 degrees, 90 degrees, 35 degrees
