Answer:
20°
Step-by-step explanation:
The sum of all triangles must equal 180 degrees.
The measure of two angles of a triangle are each four times the measure of the third angle.
2x+x/4=180
The equation above illustrates a way to solve for X which represents the the independent angle measurement from the two angles.
x = 80
Above, we solved for x by simplifying both sides of the equation and then isolating x. So hmm...does 80 make sense?
80 / 4 = 20. So it is four times the measure of the 3rd angle. But does it all equal to 180?
2 * 80 + 20 = 180.
The angle of the third angle is 20 degrees.

Answer:
10.3 laps
Step-by-step explanation:
On each lap, Ashley runs two lengths of 100 m and the circumference of a 60 m circle. That circumference is ...
C = πd
C = π(60 m) ≈ 188.496 m
So, the length of one lap is ...
2·100 m + 188.496 m = 388.496 m
The number of times around for 4000 m will be ...
(4000 m)/(388.496 m/lap) = 10.30 laps
Ashley must run 10.3 times around in order to run a total distance of 4 km.
