recall that
sin(x) = cos(90-x)
therefore
cos((2/3)x + 20) = cos(90 - [2x - 10])
(2/3)x + 20 = 100 - 2x
2x + (2/3)x = 80
divide through by 2
x + (1/3)x = 40
(4/3)x =40
4x = 40*3
4x = 120
x = 30
since it is a right angled triangle, the angles are 30, 60 and 90
Answer
3/18, 15/36, 5/9, 5/6, 31/36
This is least to greatest.
Step-by-step explanation: find a common dinominator which is 36
5/6 converted into 30/36
Keep 15/36 the same
3/18 converted into 6/36
Keep 31/36
5/9 converted into 20/36

Answer: 4</h3>
================================================
Explanation:
We'll only focus on points J and K.
J = (3, -6)
K = (-1, -6)
Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates
3 minus (-1) = 3 - (-1) = 3 + 1 = 4
Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.
This means segment JK is 4 units long.
