The rules are very simple: an angle is acute if it's less than 90°, whereas it is obtuse if it's more than 90°.
So, for the first task, you just need to compare the given angle with 90°. If the angle is less than 90°, it's acute. Otherwise, it's obtuse.
Moving on, angle B is complement of a angle A if A+B=90. So, for example, the complement of the first angle is 80, because 10+80=90. Note that this implies that obtuse angles don't have a complement.
Finally, angle B is supplement of a angle A if A+B=180. So, for example, the complement of the first angle is 170, because 10+170=180.
I don’t think it is, sorry I’m not 100% sure, good luck though
Answer:
6/35 miles per hour
Step-by-step explanation:
To find the unit rate, put distance over time
distance = 1/7 miles
time = 5/6 of an hour
miles/hours
(1/7)/(5/6)
(1/7)*(6/5)
6/35 miles per hour
