Answer:
y = 394
Step-by-step explanation:
I do not understand what you are asking for
I am assuming you want the missing angle, in this case it is 10
Triangle Sum Theorem states that a triangle is equal to 180 degrees
120+50 = 170
180-170
= 10
Average time of a commuter train trip from one town to the city = 77 minutes
Time taken by 1 trip = 71 minutes
Time taken by another trip = 74 minutes
Time taken by 3rd and 4th trip each = 78 minutes
Let us assume the time taken during the 5th trip = x
Then
(71 + 74 + 78 +78 +x)/5 = 77
301 + x = 77 * 5
301 + x = 385
x = 385 - 301
= 84 minutes
So the length of the fifth trip was 84 minutes. I hope the procedure is clear enough for you to understand.
