X= one angle
90-x= complementary angle ( complementary angles adds up to 90 degrees)
x=90-x+42.6
x=-x+132.6(combine like terms)
x+x=-x+132.6+x(add x on both sides)
x=66.3(divide each side by 2)
90-66.3=2
one angle is 42.6 complentary angle is 88 degrees

Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
