Answer:

8). x = 9

9). x = 5

Step-by-step explanation:

Note that if you take a point outside a circle and take the two tangents, they are symmetrical. And if they're symmetrical, their lengths are equal!

8).

5x - 1 = 3x + 17

2x - 1 = 17

2x = 18

x = 9

9).

-4 + 4x = 3x + 1

-4 + x = 1

x = 5

The sum of the areas of two circles is 80n square meters. Find the length of a radius of each circle if
astra-53 [7]

Answer:

8 meters.

Step-by-step explanation:

Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π

π x^2 + π 4x^2= 80π

x^2 + 4x^2= 80

5x^2 = 80

x^2 = 16

x = 4.

So the radius of the larger circle = 2*4 = 8 m.

In-s [12.5K]

Answer:

∠L = 54°

Step-by-step explanation:

5x + 2x + 3x = 180 (all angles in a triangle add up to 180)

10x = 180

x = 18°

∠L = 3x

sub x = 18

3(18) = 54

∠L = 54°

Suppose you are covering your desk (shape below) with paper and want to know how many square inches of paper you need.
zavuch27 [327]

Answer:

a. Divide the figure into two rectangles, find the area of each rectangle and add them (See the picture attached).

b. 279\ in^2

c. The total area of the figure is 279 square inches.

Step-by-step explanation:

a. Divide the figure into two rectangles (See the picture attached), then find the area of each rectangle and finally, add the areas calculated in order to get the total area of the given figure,

b. The area of a rectangle can be found using this formula:

A=lw

Where "l" is lenght  and "w" is the width.

 Area of Rectangle A

You can identify that:

l_A=19\ in\\\\w_A=11\ in

Then, its area is:

A_A=(19\ in)(11\ in)=209\ in^2

Area of Rectangle B

You can identify that:

l_B=10\ in\\\\w_B=18\ in-11\ in=7\ in

Then, its area is:

A_B=(10\ in)(7\ in)=70\ in^2

Total area

A_T=209\ in^2+70\ in^2=279\ in^2

c. The total area of the figure is 279 square inches.
