A regular polygon<span> is equilateral (it has equal sides) and equiangular (it has equal angles). To </span>find the area of a regular polygon<span>, </span>you<span> use an apothem — a segment that joins the </span>polygon's<span> center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).
Hope this helps tho I cant help with #2 sorry</span>
He sold 17 t-shirts. Subtract 40 from 125 and then divide 5 into 85. Your answer is 17.
Answer:
what are we supposed to answer? im confused.. i can help i just dont know what to answer
Step-by-step explanation:
Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)
90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x
The smaller angle is 14°.
The larger angle is 76°.
Set the equation to 125.
15x+50= 125
Subtract 50.
15x= 75
Divide by 15 into both sides.
x= 5
