Answer:
8=41
7=49
10=41
9=49
Step-by-step explanation:
angle 8 is given and since 7 and 8 make 90 then 7 =49 because 90-41=49. 10 and 8 are the same size (at least it looks like it) therefore 7 and 9 are the same too. So that is how I got the answers.
X/y, y would be the 20 percent of course and x is the money earned
