To change from percent to decimal, move the decimal place to the left two times. In this case the decimal is after the 75. so the decimal is .75 To write .75 as a fraction put 75/100 because it is in the hundredths place. Reduce by dividing both parts by 25. the fraction is 3/4

Since you have an angle and at least one side you can use either sine, cosine or tan. For this question, you would use sine like above. Hope this helps!
