What is m HLG
____ degrees

Answers

m\angle HLG + m\angle HLI=90\n9m+25m+22=90\n34m=68\nm=2\nm\angle HLG=9\cdot2=18^(\circ)
If one quadrant equals 90 degrees then 25m+22  plus 9m equals 90 degrees solve the equation for x  first combine like terms then subtract 22 from 90. (25m+22) + (9m)= 90    34m+22=90      34m=68 Divide 68 by 34 and m=2  You can also plug 2 back into both equations and add the results. ( to equal 90).  Angle HLG is 18

Max is making a rectangular garden that is 5 feet less than twice it's width. If the perimeter of the garden is 89 feet, what will be it's dimensions?

Answers

length = 2*width - 5
perimeter = 2(length + width)
89 = 2(2width - 5 + width)
89 = 6 width - 10
6 width = 99
width = 99/6 = 16.5 feet
length = 2*16.5 - 5 = 28 feet
