Answer:

  • 30°

Step-by-step explanation:

<u>A and B are same side interior angles and hence supplementary:</u>

  • m∠A + m∠B = 180°

<u>Substitute values and solve for x:</u>

  • 6x - 18 + 14x + 38 = 180
  • 20x + 20 = 180
  • 20x = 160
  • x = 160/20
  • x = 8

<u>Find the measure of ∠A:</u>

  • m∠A = 6*8° - 18° = 30°

KatRina [158]

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes
