Two angle are supplementary if their sum is 180. The large angle measure five degrees more than four times the measure of a smaller angle. If x represents the measure of the smaller angle and this two are supplementary, find the measure of each angle

35 degrees

Step-by-step explanation:

4x + 5 (the measure of the large angle) + x (the measure of the supplementary angle) = 180. Therefore x = 35

35,145

Step-by-step explanation:

angle 1+angle 2=180 degrees

x=angle 1

x+4x+5=180

4x+5 is angle 2 (larger angle) bc it is 5 more than 4 time the measure of the smaller angle

now we solve

x+4x+5=180

5x+5=180

5x=175

x=35

the smaller angle is 35 degrees

4x+5=bigger angle

4(35)+5=

140+5=

145=bigger angle

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
