Answer:

I dont know the answer but I found out how you figure out if lines are supplementary

Step-by-step explanation:

1) let the measure of one of the supplementary angles be a

2) measure of the other angle is 2 times a

3) so the measure of the angle is 2a

4) if the sum of the two angles is 180 degrees then the angles are supplementary

A drawing has a scale 1/4 in: 12ft. How long is 8ft?
allochka39001 [22]
If you use a proportion, you'll get:

\frac{0.25}{12} =  \frac{x}{8}

Then, you use cross products:

12x=0.25(8) \\ 12x=2

Then, you algebraically solve x:

12x=2 \\ \frac{12x}{12} =  \frac{2}{12}  \\ x= \frac{5}{3}

The answer is 5/3 inches , or 1 5/13 inches, or 1.6 repeating.

Tpy6a [65]
An hour has 60 minutes in it, so the simplified form would be
2 14/60 (The 2 should be the whole number in front of the fraction)

In order to change it into a decimal, change it into an improper fraction and divide
134/60
