Answer:
is this your only question?
Sin D - 4/5
This is because sin would mean Opposite/Hypotenuse, and so if the angle is D then the opposite is 4.
sin C - 3/5
This is basically the same reason as sin D, however this time the Opposite is 3.
sin D × cos D - 4/5 × 3/5 = 12/25
For here, you just get the fractions of sin D, which we got earlier, and cos D, which would be Adjacent/Hypotenuse and therefore 3/5.
tan C × tan D - Not an option
cos C × tan D - 16/15
This is because cos C would be 4/5, and tan D would be 4/3 (Opposite/Adjacent) and multiplying those fractions together gives 16/15.
I hope this helps!
I would go with Jesses survey.
Unlike everyone else’s survey Jesse chose 6th grade students in random, causing a more unbiased research.
The Shaded area is .25 of the circle, so:
Area/4 = Shaded
18/4 = Shaded
4.5 = Shaded
Hope this helps!
