Answer: x = 29
Step-by-step explanation:
We can see that x = 29 because that angle is a right angle. They ahve iven us 61 degrees out of the full 90 degrees for the right angle.
Then we can just subtract 61 from 90 which is 29.
X=29
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29

Explanation:
Miles = 15 1/10
Miles = 151/10 miles
Hour = 1/3 hour
Av = 151/10 miles / 1/3 hour
Av = 151/10 × 3 / 1/3 × 3
Av = 453/10 miles / hour
Av = 45,3 mil / h
