Askier skis along a circular ski trail that has a radius of 1.25 km. the skiier starts at the east side of the ski trail and travels in the ccw direction. let θ θ represent the radian measure of the angle the skier has swept out. suppose cos ( θ ) = 0.9 cos(θ)=0.9 and sin ( θ ) = 0.43 sin(θ)=0.43. what does the 0.9 in cos ( θ ) = 0.9 cos(θ)=0.9 represent in this context? select all that apply.
a. the skiier is 0.48 radius lengths to the north of the center of the ski trail.
b. the skiier is 0.88 radius lengths to the east of the center of the ski trail.
c. the skier is 0.48 km to the north of the center ofthe ski trail.
d. the skiier is 0.88 km to the east of the center of the ski trail.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
