What is the value of x?

Mathematics

Answer:

x=58

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the value of x.

We can see that angle that measure 51 degrees is formed by tangent and secant of our given circle.

The tangent-secant theorem of circle states that when a secant and tangent intersect out side the circle, then the measure of angle formed is half the difference of intercepted arcs.

51^{\circ}=\frac{160^{\circ}-x^{\circ}}{2}

51^{\circ}*2=\frac{160^{\circ}-x^{\circ}}{2}*2

102^{\circ}=160^{\circ}-x^{\circ}

102^{\circ}-160^{\circ}=160^{\circ}-160^{\circ}-x^{\circ}

-58^{\circ}=-x^{\circ}

x=58

Therefore, the value of x is 58.

51= 1/2(160-x)
102=160-x
x=160-102=58

What is the scale factor?
fgiga [73]

Answer:

2

Step-by-step explanation:

Basically you don't need to find x to know the scale factor ,

but I did.So you see that multiple 3 by 2 you will get 6

(MN) and the same will happen with 5.5 and NO (which is 11 btw).

so you can write 2:1

In-s [12.5K]

Step-by-step explanation:

Erase the dot points you already have. We are supposed to substitute those values in the right side of problem 1 into the function as x.

For example if x=-4

- ( - 4) + 5 = 9

If x=-2

- ( - 2) + 5 = 7

If x=0

0 + 5 = 5

- 2 + 5 =  3

- 4 + 5 = 1

So our point should be

-4,9

-2,7

0,5

-2,3

-4,1.

The range is all possible y values in a function. Since this is discrete and we are given the domain, our range will just be the y value of the points you graphed.

(9,7,5,3,1)

F(x)=-x^2+3 find f(-2)
Black_prince [1.1K]

Answer:

f(-2) = -1

Step-by-step explanation:

f(x) = -x^2 + 3

f(-2) means when x is -2

Shown in the graph below, the point of solution is: (-2,-1), so when x is -2 y is -1
