Answer:
167º
Step-by-step explanation:
The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.
The area of a trapezoid is the height times the average of the two bases, mathematically:
A=h(b1+b2)/2, in this case h=6in, b1=9in, and b2=7in so
A=6(9+7)/2
A=6*16/2
A=48in^2
<span>To be both complex and imaginary, the answer would have to include "i" as well as have the form "a + bi". The first example, 3i - 5, fits. This would look to be the only example that does fit. The negative square root of 14 would be imaginary, but not complex.</span>
600/100 as a mixed number would be 6
