If you add that together you get 28

Answer:

Step-by-step explanation:
Start by determining the simpler angle
(or, the complement of the highlighted angle in red on your image). The cosine of that angle is

Now, back to the actual red-circled angle. That one is going in the negative direction and ends up in the same position on the unit circle. Since cosine is an even function, its value is the same whether you evaluate at an angle theta, or its complement 2pi-theta. So, the final answer is:
The ratio is 9/12 and you can write it as a proportion. so you multiply 9 by 100 then divide it by 12. answer is 75% chance
