If PQ and PR are tangent to circle S,find PQ

Mathematics
1 answer:
GrogVix [38]3 years ago
8 0

Answer:

From one point, you can draw two tangents to a circle. These two tangents will be equal.

Step-by-step explanation:

7x - 24 = 57 - 2x.

Rearrange the numbers (by adding 2x and 24 on both sides), we get:

7x+2x = 57 + 24

9x = 81.

x = 9.

Length of PQ = 57-2x = 57 - 18 = 39

Find the length of side Y (this is from the geometry for enjoyment and challenge textbook) PLEASE ANSWER ASAP IT'S DUE TOMORROW!
Ymorist [56]

Answer:

y= 3

Step-by-step explanation:

The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.

First, find the length of the side that both triangles are connected to.

tan30=x/9

Isolate the x variable and solve.

9(tan30)=x

x= 5.19615

Now use the Pythagorean Theorem to solve for the side length, y.

a^2+ b^2 = c^2

(5.19615)^2+ b^2= 6^2

c= 3

What is the domain of f (x) = 4 + 2x on a graph when the range is (0,6)
galina1969 [7]

Answer:

(-2, 1).

Step-by-step explanation:

When f(x) = 0

4 + 2x = 0

2x = -4

x = -2.

Ehen f(x) = 6

4 + 2x = 6

2x = 6-4 = 2

x = 1.

What Is the answer to 10ac-x/11=-3
cestrela7 [59]
  1. Multiplty both sides by 11. 11 times 11 cancels out, 11 times -3 equals -33. You should get 10ac - x = -33
  2. Add  x  to both sides:   10 a c = x − 33
  3. Divide both sides by  10 c :   a = x − 33 /10c

revised tada!

In parallelogram LMNO, what are the values of x and y?
Black_prince [1.1K]
O and M are equal... N and L are equal. The whole shape adds up to 360 degrees.
3x-55=2x
x=55
So O= 110, M=110. That leaves the rest of the shape with 140. Divide by 2. N and L= 70... plug it in.
70=5y
y=14
So the answer is x=55 y=14
