It would be to ask all the students in the grade.
Step-by-step explanation:
Answer:
A= 45 degrees
And angle B= = 135 degrees
Step-by-step explanation:
Supplementary means that the sum of both angles is equal to 180 degrees.
< A= x
< B= 3x
<a+<B= 180
x+3x= 180
4x= 180
x= 180/4
x= 45
Therefore angle A= 45 degrees
And angle B= 3x= 3*45= 135 degrees
He will run 20miles for 10 minutes
Rate = Distance / time
for the first jog
distance = 8 miles
time = 4 minutes
rate = 8 / 4
rate = 2 miles/minutes
to calculate the distance covered in 10 minutes
from Rate = distance / time
Introducing cross multiplication
Distance = rate x time
Distance = 2 x 10
Distance = 20miles
