We know that
θ=11 pi /6 radians-----> 11*180/6----> 330°
330°----> belong to the IV quadrant
so
cos θ----> is positive
sin θ----> is negative
tan θ----> is negative
330°-----> 360°-330°---> 30°
sin 30°------> 1/2
sin θ=-1/2-----> remember that sin θ is negative
cos 30°------> √3/2
cos θ=√3/2
tan 30°------> (1/2)/(√3/2)----> √3/3
tan θ=-√3/3-------> remember that tan θ is negative
the answer is
sin θ = negative 1 over 2; cos θ = square root 3 over 2; tan θ = negative square root 3 over 3
Answer:
-2x+y=12
Step-by-step explanation:
linear equation
Answer:
a
Step-by-step explanation:
The volume is the product of the side lengths which is 1*6*11= 66 mm^3. The surface area is twice the sum of all the possible products of the side lengths, or 2lw+2wh+2hl which is 2(6*11+6*1+11*1) = 166 mm^2 if my mental math is decent.
The answer is choice A
The line is RS because R and S are on the line.
The plane is RSU because we need at least 3 non-collinear points to form a plane. In this case, point U is not on line RS.
