The answer for this question is 822
40min*1.05=42min they spent 42 min together
ps: check the multiplication it's 01:30 and I did that in head
Answer A and Answer D along with the ones you picked beforehand
Answer:
According to triangle theorems, we know that the interior angles of a triangle equals 180 degrees. Since we know that angle A and angle B are 55 and 30 degrees, all we need to do is add them up and subtract it from 180 degrees to find out the measure of angle C.
55 + 30 = 85 degrees
180 degrees - 85 degrees = 95 degrees (this is the measure for angle C)
