It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
<span>A) x+y+z=23
B) y+z=14
C) z=9
Since z = 9 then
A) x + y = 14
B) y = 5
A) </span><span><span>x + y+ z=23</span>
A) x + 5 + 9 = 23
A) x = 9

Answer:
A. 45°
Step-by-step explanation:
The smallest interior angle measure of any regular polygon is that of an equilateral triangle: 60°.
___
The corresponding exterior angle measure for interior angle x will be its supplement: 180° -x. This value must be a divisor of 360° 360° is not evenly divisible by 180°-45°=135°.
Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.
