Step-by-step explanation:
The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.
sin (72°) = x/16
x ≈ 15.2
Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10
The fraction indicating the number of students who are not wearing either blue or white shirt is:
1- 1/6- 2/3= 1/6.
36 students* (1/6)= 6 students.
There are 6 students who are not wearing either a blue or a white shirt.
Hope this helps~
It is 1.5 times because $63 divided by $42 is $1.5.
I hope this is what you meant.
