A circle is 360° all the way around; therefore, if you divide anarc's<span> degree measure by 360°, you find the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the</span>arc<span>.</span>
Step-by-step explanation:
slope is y2-y1/x2-x1
formula is
y=mx+b where m is the slope
Ab= 10
Ad= 2Ab+8
Perimeter of parallelogram is 2(a+b)
So 2(2ab+8)+2(ab)=6ab+16
6ab+16=76
6ab=60
Ab=10
