3x-2 = 5x-14

Subtract 3x from each side:

-2 = 2x -14

Add 14 to each side:

12 = 2x

Divide both sides by 2:

x = 12/2

x = 6

The angle marked a = 146 Work out the angle marked x.

notka56 [123]

Answer:

<h2>34 degrees</h2>

Basic facts:

Corresponding angles are sometimes known as 'F' angles.

angles in a straight line add up to 180

Step-by-step explanation:

To find the other side of a we follow the Basic fact annd do

180-146

=34

following the rule, we know that this is a flipped F

An F is a corresponding angle

therefore f is 34

Given each of the following areas, what would be the radius of each circle? a. A = 530.66 m2 b. A = 907.46 sq. ft. c. A = 379.94

ra1l [238]

Area for a circle is $A= \pi r^2$ . We will fill in each area and then solve for the radius. $530.66m^2= \pi r^2$ and $\frac{530.66m^2}{3.14}=r^2$ . ∴ $169=r^2$ and r = 13. For b, $907.46ft^2= \pi r^2$ and $\frac{907.46ft^2}{3.14}=r^2$ . $289=r^2$ , ∴ r = 17. For c, $379.94mi^2= \pi r^2$ , and $\frac{379.94mi^2}{3.14}=r^2$ . ∴, $121=r^2$ and r = 11. For d, $1962.5cm^2= \pi r^2$ , and $\frac{1962.5cm^2}{3.14}=r^2$ . ∴, $625=r^2$ so r = 25. And there you have it!
