Answer:
2 pi, -2 pi, pi, -pi
Step-by-step explanation:
Draw a unit circle and label the 4 points where it intersects the x/y axis. for example at 0 degrees or 360/-360 degrees the (x,y) or (cosine theta, sine theta) value is (1,0).
Knowing that all triangles angles add up to 180*:
24* + x + ? = 180*
Knowing the straight line is 180*:
180* - 122* = 58*
The equation then is:
24* + x + 58* = 180*
Then solve for X:
(82* + x) - 82* = (180*) - 82*
<u>x = 98* or C</u>
Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
Answer:
1/15
Step-by-step explanation:
since there are 3 equal colors, they're all 1/3
since it's 5, it's 1/5
1/5 x 1/3
1/15
