Hey!
To find the percentage increase, you must use this formula:
{(50 - 92 / 50] × 100 = 84%
So, the percent increase from 50 to 92 is: 84%.
Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
7, you divide the 14 by 2 because the qr is two times the length of gh, therefore 7 is two times the length of fh
I think what's your trying to say is 419-200? If so it's 219
