Answer:
x =62 y=118
Step-by-step explanation:
The sum of two opposite angles in a cyclic quadrilateral is equal to 180 degrees (supplementary angles)
x+44+74= 180
x+118=180
x=62
y-48+110=180
y+62=180
y=118
these are the answers 100=10 ,144=12 ,4=2
For maximum height:
dxdy=0⇒dxd(10x−95x2)=0
⇒10−910x=0
⇒x=9 m
