16. In AJKL, if mZK is nine more than mZJ and mZL is 21 less than twice mZJ, find the measure of each angle.
MZJ =
mZK =
+
mZL =

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

yes

step-by-step explanation:

yes

it is 10.6 according to my calculations

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
