The distance is 1410 miles.
The triangle above shows how speed, distance and time are related. D = s x t
S= d/t
T=d/s
is the same thing here as the other triangles, the triangle below is an equilateral, the one above is an isosceles.
the <u>vertex</u> of the isosceles is 40°, so the twins angle at the <u>base</u> are (180 - 40)/2 = 70° = x each.
since the sides in the equilateral are all the same length, then 2y + 10 = x - y, but we already know what "x" is, so

Answer:
159.5 degrees
Step-by-step explanation:
The supplement of an angle has the same sine value as the angle.
50° is the answer to your question.
Answer:
Once
Step-by-step explanation:
8 can only go into 9 once, if you were to do it a second time, there would be a remainder of 7.
