Find the exact value of cos (1140)°.

Mathematics
1 answer:
slamgirl [31]3 years ago
8 0

now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.

namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°.  Thus cos(1140°) = cos(60°).

what's that cosine of 60°?  Check the picture below.

Move point b some more as you move point b the angle formed between ab and cd varies if you want to make an perpendicular to cd
dybincka [34]

Answer:

Following are the response to the given question:

Step-by-step explanation:

Move b a bit further if the angle between cd and ab changes when you move b if you want to make a perpendicular point to cd The angle BEC is 90 ° for making the AB line perpendicular to the line CD to transfer point B to the angle between the two lines.

Since O is circumscribed about quadrilateral DEFG, the value of x is equal to: D. 68°.

<h3>What is a supplementary angle?</h3>

A supplementary angle can be defined as two (2) angles or arc whose sum is always equal to 180 degrees. Mathematically, a supplementary angle can be calculated as follows:

Q + R = 180°.

In Geometry, the opposite angles of any cyclic quadrilateral that is inscribed inside a circle always form a supplementary angle. Thus, we would determine the value of x by using the mathematical expression above:

x + 112° = 180°

x = 180° - 112°

x = 68°

What transformation maps the preimage (red) onto the image (blue)?
Dominik [7]

Answer:

Rotate counter clockwise about the center point 180 degrees

Step-by-step explanation:

You can use transformations to preserve shape and size but move a shape or change its position. Transformations include:

  • reflection - a flip across an axis
  • rotation - a turn around a point
  • translation - a slide a specific distance and direction

To map the red into the blue, you can rotate it counter clockwise about the center point which the red and blue shapes share 180 degrees. It will land exactly on the red.

Some equations have the form y=kx, where k is a number. Which equation CANNOT be written in the form y=kx?
kumpel [21]

Answer:

Any equation of the form

y = kx + b,

with b different from zero

Step-by-step explanation:

For example

y = 5*x +3

cannot be written in the form

y = k*x, because there is a term that shifts the graph upwards.
