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°)

Circumference of a circle is

Answer:

Step-by-step explanation:
Lines MR and PQ are parallel. Continue the line MR up to the intersection with the line NQ. Denote the point of their intersection as A.
Consider triangle AMN. In this triangle,
- given;
- angles RMN and NMA are supplementary angles;
So, (as the sum of all interior angles add up to 180°)

Angles NAM and MAQ are supplementary angles, then

Angles MAQ and AQP are alternate interior angles, so they are congruant and

2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
