5/6 as there is 6 jumps and the dot is placed on the fifth therefore being 5/6
The sum of everything is 720 degrees, because of the six sides in this figure.
We sum all angles and get 595
720 - 595 = 125
The answer is 125 degrees
12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9
Round all of the numbers to the nearest 10 then solve the problem like normal
