Answer:
Angles in a triangles add up to 180°
Respectively 1 : 2 : 3 is going to be 1 x , 2 x and 3 x so,
1 x + 2 x + 3 x = 180°
⇒ Simplify
6 x = 180°
⇒ Divide by 6 on both sides to isolate x
x = 30°
Since the ratio was 1 x : 2 x : 3 x and x is 30°,
30 : 60 : 90
And since there is a 90° angle, it is a right - angled triangle

Step-by-step explanation:
1. Determine the total distance heather has run in Km.
4.18km PER DAY for 197 days; 4.18 * 197 = 823.46km.
2. Can we just stop and say that this Heather chick MIGHT HAVE A PROBLEM?! Like, fr, she has run over 500 miles in half a year. . .she needs to see someone about that.
3. Divide the total distance by the distance of the track.
823.46/0.21 = 3921.23809524
4. Conclusion: Heather has run (roughly) 3,931.24 times around the track after the 197 day period of running 4.18km per day.
73.94 X .33 = 24.40 thats how much the markup (or profit is)
73.94 + 24.40 = 98.34 thats how much they sold it for.
