Question

HELP ME i think i get the idea but i need further evaluation.

Answer 1

x = 4.28

Explanation:

`Given,\ To\ find\ for\ x,`

`Let\ c\ be\ the\ centre\ of`

`Circle,\ where`
`AD=22.4\ (Diameter)`

`AC=(22.4)/(2)=11.2\ (radius)`

`AB=8.8`

`In\ \Delta\ ABC, Right\ angled\ at`

`B.\ USing Pythagoras\ theovem`

`(AB)^2+(BC)^2=(AC)^2`

`(8.8)^2+(BC)^2=(11,2)^2`

`(BC)^2=125.44-77.44=48`

`BC=√(48)=6.92`

`E_c=x+y\ \ \ \ \(Where\ Fc\ is\ also\ radius\ of\ arcle`

`\therefore\ \ \ \ \11.2=x+6.92`

`x=11.2-6.92=4.28`

`Hence,\ x=4.28\ is\ the\ answer.`

I hope this helps you
