(1-sin(x))(1+sin(x))=1/1+tan(x^2)

I think  the right side is  tan^2 x    ( the square of tan x)

Left side =  1 - sin^2 x

Right side = 1  / ( 1 + (sin^2 x / cos^2x))

= 1  /    (cos^2x + sin^2x) / cos^2 x

Now sin^2 x + cos^2 x = 1  so

this =  1  /   1 / cos^2x

= cos^2x  = 1 - sin^2 x  = Left side    - Proved

if you multiply me by 2, I become a number greater than 20 and less than 40. if you multiple me by 6 I end in 8
snow_lady [41]
Lets say you are x
20<2x<40
therefore x has to be greater than 10, but less than 20
6x=_8
the only numbers between 10 and 20 that works with this equation are 13 and 18
(6x13=78 and 6x18=108)

In ΔPQR, find the measure of ∡P. Hypotenuse is 57.6 and the opposite side is 33.8.
alekssr [168]

Step-by-step explanation:

pythogoras theorem = Q²=P²+R²

P=P

Q= 57.6

R=33.8 =

(57.8)²=(P)²+(33.8)²

=3,340.84=(P)²+1142.44

=3340.84-1142.44=P²

=2,198.4=P²

=   \sqrt{2198.4}  = p    \\  = 46.8 = p
