Line RS is tangent to circle Q at point R.What is the measure of ∠SQR ?

Enter your answer in the box.

Answers

Using the tangent and radius theorem, the measure of ∠SQR is 58°.

What is Circle Geometry??

From the question, we are to determine the measure of ∠SQR

In the given diagram, QR is a radius

By the tangent and radius theorem,

If a tangent and a radius meet at the point of tangency, then they are perpendicular to one another

∴ ∠QRS = 90°

∠SQR + ∠RSQ + ∠QRS = 180° (Sum of angles in a triangle)

∠SQR + 32° + 90° = 180°

∠SQR + 122° = 180°

∠SQR = 180° - 122°

∠SQR = 58°

Hence, the measure of ∠SQR is 58°.

If the line RS is tangent to the circle, then it is at a 90 degree angle to the circle at the point of contact.

Now that we know 2 angles, we can find the 3rd:

180 - 90 - 32 = 58

Y=-2x

What is the value of x?

Answers

Step-by-step explanation:

x+y=3

y=2x

x+2x=3

x=3-2x

it's your required answer

Answer:

x=-3

If you need to find the value of y than substitute x=-3 into equation (1) .

I have no idea how to use this site yet, so I'm just gonna put my algebra problem here. Thanks for any help!Graph system of equation:
x-2y=2
3+y=6

Answers

I have a hard times putting graphs so I'll just put the answers and say how to graph with paper
so we notice that if we solve the second equation (3+y=6), we get a value for y and no value for x so just draw a horizonal line at the point 3 on the y axis

then make the second equation into slope inercept form y=mx+b
x-2y=2
2y-x=-2
2y=x+2
y=1/2x+1
just put in values for x and get y values, then plot points and get line
find where the line inercepts/crosses the first line (3+y=6) and that is the solution

OR

so a the solution is when both equations are true so just assume both are true and solve for x and y

x-2y=2
3+y=6

first of all the second equation is easy
3+y=6
subtract 3 from both sides
y=3

so we subsitute 3 for y in first equation
x-2(3)=2
x-6=2
add 6 to both sides
x=8
y=3
the solution is the point (8,3)

The answer for this one is C. because you aren't looking for a number greater or less than 3 so the 3 you are looking for is going to be counted as a number which one just be 1/8 :)
