56° and 34°
complementary angles sum to 90° thus
3x - 10 + 2x - 10 = 90
5x - 20 = 90
add 20 to both sides of the equation
5x = 90 + 20 = 110
divide both sides by 5
x =
= 22
angle 2x - 10 = (2 × 22) - 10 = 44 - 10 = 34° and
angle 3x - 10 = (3 × 22) - 10 = 66 - 10 = 56°
Answer:
220 minutes
Step-by-step explanation:
Find how many hours there are between the two times which is 3 hours then multiply 3 by 60 because there are 60 minutes in an hour
Since the time is 11:40 we also know 40 minutes have passed so add the two minutes
40+180=220
