Answer:

x = 3, line AB = 17 , and line CD = 17

y = 10, angle A = 70, and angle D = 70

Step-by-step explanation:

well since their the same length you can put them equal to each otheir

5x + 2 = 8x - 7

subtract 5x by both sides to get --> 2 = 3x -7

add 7 to both sides and get --> 9 = 3x

divide 3 by both sides to get x = 3

now plug it back in each equation we started with and get you answers

Answer:

See below

Step-by-step explanation:

No actually the top is kinda of wrong. To find the angles I think you do this...

(2y+50) + (3y+40)=180

5y+90=180

5y=90

y=18

Then you plug it in the equations...

If sector area of the shaded circle garden is 8π, and radius of the circle garden is 8 inch. Below figure represent the given sc

otez555 [7]

Answer:

The measurement of the central angle AOB is 45 degrees

Step-by-step explanation:

To solve this problem, we will have to work with fractions.

We will get the fraction of area the shaded portion is when compared to the whole garden.

First of all, we will need to calculate the area of the garden which is $\pi r^{2}$

in this case, our radius is 8 inches.

Next, we will compare the area of the sector to the area of the garden. This will be

This will be the shaded area/ area of the whole garden

= $\frac{8\pi}{\pi8^{2}}$

$=\frac{1}{8}$

We will now convert this ratio to an angle by multiplying it by 360 degrees.

This will be:

$\frac{1}{8}\times 360 = 45 degrees$

The measurement of the central angle AOB is 45 degrees
