Answer:
LHS.= Sin 2x /( 1 + cos2x )
We have , sin 2x = 2 sinx•cosx
And. cos2x = 2cos^2 x - 1
i.e . 1+ cosx 2x = 2cos^2x
Putting the above results in the LHSwe get,
Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x
=sinx / cosx
= Tanx
.•. sin2x/(1 + cos2x)= tanx

Answer:
17.6
Step-by-step explanation:
22 x .80 =17.6
17.6 is 80% of 22 so that would be your answer
Answer:
Step-by-step explanation:
(1, 5.5) ; (2, 9)
Slope = 

= 7/2
m = 7/2 ; (2 , 9)
y - y1 =m(x -x1)

Multiply the equation by 2
