In circle C, what is the value of x?

Mathematics
1 answer:
Anna71 [15]3 years ago
5 0

Answer:x=22 degrees

Step-by-step explanation:

We are given a circle C.

Centre is at C

A line passes through the centre makes angle x and 68 on either side

A triangle is formed with angles x, 68 and another angle at the circumference.

Since the line passing through the centre is diameter of the circle, we have

the third angle of the triangle = 90 degrees ( BY semi circle angle theorem)

In the triangle sum of three angles

=90+x+68 =180

x =22 degrees

A vertical plane passes through a pyramid that has a horizontal base.
Kay [80]

A triangle will be produced from the intersection of the vertical plane and pyramid. The correct options are triangles and trapezoid.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.

Given that a vertical plane passes through a pyramid that has a horizontal base. Therefore, when the vertical plane and the pyramid meets or intersect the two dimensional figure that will be produced when the two intersect is triangle. It can also be trapezoid if the vertical plane does not intersect exactly in mid of the pyramid.

Hence, a triangle or a trapezoid will be produced from the intersection of the vertical plane and pyramid.

Calculate the measure of arc AC if the measure of arc CD is 170 degrees and arc AB is 80 and AB||CD.
CaHeK987 [17]

Answer:

  AC = 55°

Step-by-step explanation:

In this geometry, arcs AC and BD have the same measure. The sum of the parts of arc CD will total the measure of CD.

  AC + AB + BD = CD

  2AC +80 = 170

  AC = 110/2 = 55

The measure of arc AC is 55°.
