Answer questions 11 and 12
really urgenttt

11.) 135°   12.) 45°

Step-by-step explanation:

11.) When finding one interior angle, you will have to first find the sum of the interior angle using the formula:

Sum of interior angle = ( n - 2 ) 180° where "n" is the number of sides of that shape. So the working will be:

( 8 - 2 ) 180°

= 6 x 180°

Sum of interior angle = 1080°

To find the angle of one interior angle, divide it by the number of sides of that shape.

1080° ÷ 8 = 135°

∴ The measure of one interior angle is 135°

12.) To find the exterior angle, use the formula:

Exterior angle = 360° ÷ n where "n" is the number of sides of that shape. So the working will be:

360° ÷ 8 = 45°

∴ The measure of one exterior angle is 45°

Extra: You can check if the answer is correct by multiplying the answer you got for the exterior angle with the number of sides and that should give you 360°.

what are the statments

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
