Answer:
I'll answer the first one. Neither vehicles are crossing the speed limit since both are under 40mph.
Step-by-step explanation:
6 miles every 10 minutes = 36 miles every hour.
15 miles every 25 minutes = 36 miles every hour.
Speed limit = 40 mph
Neither vehicles are crossing the speed limit since both are under 40mph.
Hope this helped! :))
Answer:
<u><em>Measure of angle A is 27 7/9 degrees.</em></u>
Step-by-step explanation:
Lets call measure of angle A is <em><u>X-10</u></em>
Lets call measure of angle B is X
Lets call measure of angle D is 2.5X+20
We know that the sum of triangles add up to 180 degrees
X+X-10+2.5X+20=180
X=37 7/9
So measure of angle A is 27 7/9 degrees.
I hope this is right. :)
