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.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
