Ok, first you need to change the 2,000 cm into meters and then you just multiply all the sides.
90≤4x+30
Yes she will have enough. 4 multiplied by 18 is 72. 72+30=102.
Hope this helped.
Answer:
7.854
Step-by-step explanation:
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
