Θ=3 radians
Step-by-step explanation:
Step 1:
Let the arc length (S) be 6 units
Radius of Arc(r) = 2 units
By the basic formula to find the central angle we have
Θ
where, S= Arc length
r= Radius of arc
Θ = Central angle
Step 2:
From the formula to find Θ,
Θ = (S/r)
Θ = ( 6 ) / ( 2 )
Θ = 3 radians
Do you know how to use calculator to find fast answer?
1) press mode 3 times
2)then u find 'EQN'then press 1
3)then u can see 'UNKNOWS'but dont use the 'UNKWOWS' you must press to tge right i u can see 'DEGREE' then if you already find the DEGREE you press number 2
4)Then the 'a?' will out u can put 1 stand for X^2 then equal
5) next the 'b?' come out you put 6 stand for 6x then equal
6)final the 'c?'will come out and you put -27 then equal
7) then the answer will come out
it will be x1=3 and x2=-9
8) but if you want to put in bracket the x1=will be -3 and the x2= will be 9
so final answer
(x-3)(x+9)
