Area of Square/Rectangle-LxW
Area of triangle-BxH(divided by)2
Area of polygon=56
Answer:
Y=3x+3
Step-by-step explanation:
Gradient = : = : = : = 3
Y= mx + c
y = 3x + c
Insert x and y values for first point(4,15)
15 = 3 (4) + c
15 = 12 + c
3 = c
Y=3x +3
-120° = -2π/3 radians.
Tangent is defined as Opposite/Adjacent or Sine/Cosine in a unit circle. So, if you have memorized the unit circle,
sin(-2π/3) = √3/2
cos(-2π/3) = -1/2
So, tan(-2π/3) would be:
Simplify, and you get:
And, so, tan(-2π/3) = -√3
