If c lies on diameter the angle in a semicircle.therefore another angle is 90.then by angle sum property it’s 22 degree
Zinaida [17]3 years ago

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

Answer:

C

Step-by-step explanation:

We want to find the inverse of g(x). One way to do this is to switch the g(x) and x in the original equation and then solve for g(x); that will give you the inverse.

Here, g(x)=\frac{3}{5} x-9. Switch the g(x) and x to become: x=\frac{3}{5} g(x)-9. Now solve for g(x) by isolating it:

x=\frac{3}{5} g(x)-9

x+9=\frac{3}{5} g(x)

\frac{5}{3} * (x+9)= g(x)

g(x)=\frac{5}{3} x+15

Thus, the answer is C.

Hope this helps!

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)
kvv77 [185]

Answer:

Option D) 254.3 cm2

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=9\ cm

substitute

A=(3.14)(9)^{2}=254.3\ cm^2

Factor the expression -24x -30
morpeh [17]

Answer:

-6(4x+5)

Step-by-step explanation:

-24 = -6 * 4

-30 = -6 * 5

6 is a common factor of both 24 and 30.

-6(4x) = -24x

-6(5) = -30

10 POINTS IDENTIFY THE SLOPE, Y-INTERCEPT AND GRAPH.<br> 1. Y = 2x + 3<br> 2. Y = 3/4x - 2
Alenkasestr [34]

Answer for problem 1: slope = 2, y intercept = 3

Answer for problem 2: slope = 3/4, y intercept = -2

Explanation:

Both equations are in the form y = mx+b. This is known as slope intercept form. This is because we can read off the values of the slope and y intercept very quickly. We have y = 2x+3 match up with y = mx+b. The m is the slope and b is the y intercept. So m = 2 and b = 3 for this equation. A similar situation happens with the other equation as well. It might help to rewrite the second equation into y = (3/4)x + (-2).
