Sin400°=<br><br> 1. sin40°<br> 2. -sin40°<br> 3. sin(-40)°
LenaWriter [7]

Answer:

sin(40°)

Step-by-step explanation:

Trigonometric functions such as sine, cosine, tangent whose short forms are sin, cos, tan respectively are <u><em>repetitive functions</em></u> which repeat itself after every integral multiple of 2π radian or 360°. It means if you add or subtract 360° from any input of  trigonometric function the output of the function won't change.

It means sin(θ) = sin(θ - n×360°) = sin(θ + n×360°)

similarly cos(θ) = cos(θ - n×360°) = cos(θ + n×360°)

and tan(θ) = tan(θ - n×360°) = tan(θ + n×360°)

where n is an integer.

So, by this sin(400°) = sin(400° - 360°) = sin(40°)

Find the point, M, that divides segment AB into a ratio of 2:3 if A is at (0,15) and B is at (20,0)
oksano4ka [1.4K]

The ratio has a total of 2+3=5 units, of which 2 correspond to the length of segment AM. The difference of x-coordinates Bx-Ax = 20-0 = 20. 2/5 of that amount is (2/5)*20 = 8, so the x-coordinate of M is

Mx = 8 + Ax = 8 + 0 = 8

The difference of y-coordinates is 0 - 15 = -15. 2/5 of that amount is (2/5)*(-15) = -6, so the y-coordinate of M is

... My = -6 + Ay = -6 + 15 = 9

The point M is (Mx, My) = (8, 9).
