Find the exact trigonometric ratios for the angle x whose radian measure is given. (if an answer is undefined, enter undefined.) 27π /4

Here Radian measure of an angle=27π/4

we have to find the value of six trigonometric functions.

First i have converted radian measure of an angle into degrees.

27π/4=(27×180)÷4=1215°=3 Quadrants +135°=135°

which lies in second Quadrant.

As in second quadrant only sine, cosec ,function are positive.All other trigonometric function i.e cos,sec,tan,cot function will be of negative value.

yes

step-by-step explanation:

yes

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
