1 answer:
Dennis_Churaev [7]3 years ago
6 0

Answer:

Step-by-step explanation:

Rachel

d = 90 miles.

d = 90 * 1.6 km = 144 km

t = 1.25 hours.

Average speed = d/ time

Average speed = 144/ 1.25 = 115.2

Marc

d = 244 km

t = 2hr 30 minutes

30 minutes = 1/2 hour = 0.5 hours

Average speed = 244 km / 2.5 hours

Average speed = 97.6

Difference

Difference = Rachel - Marc

Difference = 115.2 - 97.6

Difference = 17.6

The measure of angles just is 56.9 find the measure of the complement and supplement of angle j
Oduvanchick [21]
Yo bro this is simple. what you need to do is assess the vocabulary
complement=90 degrees
supplementary=180 degrees
so you use the number you were given and subtract it from the complement and supplement angles.
180-56.9=123.1 which is the answer to the supplementary of angle j
90-56.9=33.1 which is the answer to the complementary angle of j.

so 123.1 and 33.1

P.S- I might be wrong but use at your own risk
