Answer:
x=28/363 or x=0.077134
Step-by-step explanation:
484×3x=114-2
1452x=112
x=112/1452
x=28/363
Is there supposed to be an inage attached to this? you said “which” but there’s no choices..
Answer:
d it is D
Step-by-step explanation:
I would convert -2pi / 3 to degrees first by multiplying by 180degrees / pi. It equals 120 degrees.
120 degrees is in quadrant II, which is 90 degrees plus 30 degrees. It is 60 degrees from the 180 degrees.
So the reference triangle you use is 60 degrees.
Cos60 = 0.5
sin60 = sqrt(3) /2
But in quadrant II the only trig ratio that's positive is sin; all others are negative.
So cos120 = -0.5
sin60 = sqrt(3) /2
