Answer:
68.70 yd.
Step-by-step explanation:
First we would convert these into decimals. 5 1/2 would turn into 5.50, and 1 2/3 is 1.66.
(1.66 yd.) * 5.50 yd. =
7.6338428 yd.
7.6338428 yd.*3*3=
= 68.7045852 yd.
shorten the decimal for a shorter, less accurate answer.
Since opposite angles of a cyclic quadrilateral are supplementary,
A= 180-101=79°
B= 180-68=112°
