I need help on finding an equation!?
Sedbober [7]

Your distance from Seattle after two hours of driving at 62 mph, from a starting point 38 miles east of Seattle, will be (38 + [62 mph][2 hr] ) miles, or 162 miles (east).

Your friend will be (20 + [65 mph][2 hrs] ) miles, or 150 miles south of Seattle.

Comparing 162 miles and 150 miles, we see that you will be further from Seattle than your friend after 2 hours.

After how many hours will you and your friend be the same distance from Seattle?  Equate 20 + [65 mph]t to 38 + [62 mph]t and solve the resulting equation for time, t:

20 + [65 mph]t  = 38 + [62 mph]t

Subtract [62 mph]t  from both sides of this equation, obtaining:

20 + [3 mph]t = 38.  Then [3 mph]t = 18, and t = 6 hours.

You and your friend will be the same distance from Seattle (but in different directions) after 6 hours.

vodomira [7]

Answer: 8) 42°, 65°, 115°     9) 1.5, 2

Step-by-step explanation:

8) Right off the bat I know that the measure adjacent to 157° is

   23°. With both numbers inside the triangle combined, we get

   65° meaning the last number is 115 because that'll add up to 180°

9) Considering the smaller triangle has half the length of the bigger triangle

   The length of the rest are half the size too.

    EF = 1.5

    DF = 2
