Hope this helps!
Last one should be y=2 +1
Your answer would be -13 !!!
B. 54 meters
first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.
then use formula for perimeter
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54<span />
Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.
All four angles need to equal 360.
Subtract angle 1 and 3 from 360:
360 - 111 - 111 = 138
Angle 2 and 4 would also be identical, so divide the 138 by 2:
138 / 2 = 69
Angle 2 and angle 4 are both 69 degrees.
