THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(
harkovskaia [24]

Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2  miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs  12/ 2 = 6 laps.

One angle of a triangle measures 95°. The other two angles are in a ratio of 8:9. What are the measures of those two angles?
Luba_88 [7]

Answer:

40 degrees and 45 degrees

Step-by-step explanation:

If you subtract 95 degrees from a 180-degree triangle, you are left with 85 degrees. To proportionally split them, find two values that add to the same value. Since 40 and 45 make up 80 and they multiply by two to make 80:90, these are the two measures.
