Question 5 is B
Question 9 is C
Answer:
Yeah, D is the right anwser!
Step-by-step explanation:
I would be here for way to long to type up the explanation. And I don't have time to waste.
30÷5 (the 5 parts from 2:3) is 6 so the first group gets 12 (2x6) and the second gets 18 (3x6)
Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees
Hope this helps! :)
