3# Find the missing variable (s). Round to the nearest tenth.
rewona [7]

Answer:


Step-by-step explanation:


This triangle is already positioned to match trig functions (also known as circular functions).


Point A is origin, side AC (length x) is on X axis,

side CB (length y) is parallel to Y axis.


***** You just remember *****


cos is horizontal, on X axis,

sin is vertical, on Y axis.

To get from unit triangle with hypotenuse 1,

horizontal side cos(θ), vertical side sin(θ), you multiply all sides by same number, namely, the specified length of the hypotenuse.


***** that's all you need to know *****


Draw a unit circle centered at A, mark point Y at intersection of circle and AB, and drop a vertical line from Y crossing X axis at X.


Then radial segment AY is 1, AB is 10

horizontal segment AX is cos(32°), AC is 10AX

vertical segment XY is sin(32°), CB is 10XY.


So x = 10 cos(32°), y= 10 sin(32°).

Masteriza [31]

Answer:

The probability of an event is a number describing the chance that the event will happen. An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1
