For this case we have that by definition of trigonometric relations of rectangular triangles, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. So:

Where h is the hypotenuse.

We cleared h:

We rationalize:

Step-by-step explanation:
Answer:
409
Step-by-step explanation:
18 x
--- = ---
22 500
18 x 500 = 9000
9000/22 = 409
8 out of 52. There are 4 nine cards and 4 heart cards. There are 52 cards in the standard deck. So it is an 8 out of 52 chance that you will choose either a heart or a nine.
Answer:
Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.
Step-by-step explanation:
Given:
Let
A(x₁ , y₁) = (1 , 4) and
B( x₂ , y₂ ) = (-1 , 2)
To Find:
θ = ?
Solution:
Slope of a line when two points are given is given bt

Substituting the values we get

Also Slope of line when angle ' θ ' is given as

Substituting Slope = 1 we get


We Know That for angle 45°,
tan 45 = 1
Therefore

Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.
