Given:
R↔S tangent to circle A and circle B at points R and S.
Prove:
AR ∥ BS

Answers

The proof is shown below:

What is tangent?

The tangent is defined as a line touching circles or an ellipse at only one point.

As, tangent line is perpendicular to radius of the circle.

So,

AR ⊥ RS

BS ⊥ RS

Thus, AR and BS ⊥ to same line RS.

Now, either AR or BS are in same line or parallel.

since, they are the radius of different circles.

Hence, AR ║BS.

Find the indicated limit, if it exists.

Answers

Answer:

The limit is 1.

Step-by-step explanation:

In this kind of problem, we can use the left and right-hand limit method.

Basically, we need to find the limit by the left side and then by the right side. If both of them are equal the limit does exist if not the limit does not exist.

Left hand

[tex]lim_{-8^{-}}(f(x))=lim_{-8^{-}}(x+9)=-8+9=1[/tex]        

Right hand

[tex]lim_{-8^{+}}(f(x))=lim_{-8^{+}}(-7-x)=-7-(-8)=1[/tex]  

As we see, both limits are the same, so the limit is equal to 1.

Heather is considering purchasing an item that costs $17. The sales tax in Heather's area is set at 7.5%. What is the total purchase price that leather would be charged on this purchase? Round your answer to the nearest cent, if necessary.​

Answers

Answer:

$18.28

Step-by-step explanation:

To get the answer all I did was take 7.5% of 17 which is 1.275

I then rounded 1.275 to 1.28. When you round up the number after the 7 has to be 5 or above. Seeing as the number was 5 we rounded it up to 1.28.

Then I took $17+$1.28= $18.28.

What is the value of X and Y?

Answers

9514 1404 393

Answer:

  x = 20

  y = 70

Step-by-step explanation:

The exterior angle marked 40° is the sum of the remote interior angles in the isosceles triangle at lower right, both of which are x°.

  40° = 2x°

  x = 20 . . . . . divide by 2°

The angle marked y° is the complement of the one marked x°.

  y = 90 -x = 90 -20

  y = 70

Е. е

Answers

Answer:

Option C will be your answer

Step-by-step explanation:

Angle C will be equal to 52 by vertical angle theorem

hope it helps you

have a great day !!

Angle c is the vertical opposite angle with 52° so it will have a measure of 52° thus option (C) is correct.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Two opposite angle made by two intersecting lines is said to be vertically opposite angle so the angle opposite to 52° is c so, ∠c = 52°.

Hence " Angle c has a measure of 52° since it is the vertical opposite angle with 52°".

two adjacent angles from a right angle. the larger angle is 3 times the measurement of the smaller angle which is the measurement of the angle?

45°
22.5°
67.5°
30°​

Answers

Answer:

Because two adjacent angles from a right angle sums up to 90° and the larger angle is 3 times the measurement of the smaller angle, the equation would be 3a + a = 90° (A will be the substituting variable for the smaller angle). Add the like terms to get 4a=90. Divide 4 on both sides to get 22.5°. Substitute 22.5 into the variable, a, to get 67.5. This means that the larger angle would be 67.5° and the smaller angle would be 22.5°.

z= 85
x= 15

16x= 240

x= 15

Answer:

m>z=85

x = 15!

Step-by-step explanation:

85=z because they are opposite eachother and the two lines intersect.

85*2=170, so we have 170 degrees for the two angles we know the measure of. Now, we need to find the remaining angles.

360-17=190. There is 190 degrees that need to be solved still.

190/2 is 95. Each angle remaining is 95 degrees.

8x-25=95
