Use the unit circle to find tan 30°

A

Step-by-step explanation:

Draw the unit circle. Now draw the vertical line (the tangent line) that passes through the point (1,0). In anticlockwise direction from the point (1,0) draw the line that makes 30° angle with positive direction of x axis. Consider right triangle formed by the circle and these two lines. In this triangle the horizontal leg has length 1 (because this leg is the radius of the unit circle). The vertical leg has the length x. The leg opposite to the 30° angle is half of the hypotenuse, so the hypotenuse is 2x. By the Pythagorean theorem,

By the definition of tangent,

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
