Answer:
95 degrees
Step-by-step explanation:
a triangle's interior angles add up to 180 add the two known angles subtract by 180 and you get the answer.
55 + 30 = 85
180 - 85 = 95
95 degrees
Answer:
N=13
Step-by-step explanation:
For a pentagon, it's (5-2)180=(3)180=540 degrees. So plug in n=13 to see the sum of the angle measures for a 13-sided polygon.
