find the cosine ratio of angle θ. hint: use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces.

triangle abc is shown. ab measures 4. bc measures 5. ca measures 3. the angle formed at point c is marked theta and angle a is the right angle.

answer for blank 1:

The cosine of the angle theta is given as:

cos θ=3/5

Step-by-step explanation:

We know that cosine of any angle theta is defined as:

Where theta is the angle formed with whose respect we apply the trignometric identity. ( As we are given an right angled triangle so we can easily apply our trignometric identity)

Now here we have base=CA=3

and hypotenuse=BC=5.

Hence, cos θ=3/5

Also the figure of the question is attached to the answer.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
