A bag contains 100 marbles which are red, green, and blue. Suppose a student randomly selects a marble without looking, records
the color, and then places the marble back in the bag. The student has recorded 7 red marbles, 2 green marbles and 11 blue marbles. Predict how many red marbles are in the bag.
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
So you would use SOH CAH TOA and the inverse of whatever we will use to solve this problem. so we have two measurments 40ft and 25ft. so we will use the inverse of SOH which is sin. so Sin^-1(25/40)=38 degrees is your answer.
