Simplify the expression please.

Answer:

tanx·secx

Step-by-step explanation:

To simply this, you can begin by factoring sin x out of the numerator to become:

\frac{sinx (sin^{2}x +cos^{2} x)}{cos^{2} x}

Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:

\frac{sinx}{cos^{2}x }

First of all, we can convert \frac{sinx}{cosx} to tanx. However, we have a remaining \frac{1}{cosx} which, using reciprocal identities, will become sec x.

Finally, we get our answer as tanx·secx.

X + y = 3k x - y = k The solution of the system shown is _____.
VashaNatasha [74]
First, you have  x+y= 3k, x-y= k     and what you need to do now is eliminate the y's because they have the same sign (- and +). So now you have x= 3k, x=k. You so then you add the x with the other x (2x) and the 3k with the k (4k). Now you have 2x = 4k , which is the same as x = 2k. Now that you now x in terms of k, you can put it in the very first system, like this: 2k+y=3k, 2k-y=k. If you solve them, first one and then the other, you will get the same result: y=k.

So, you can say that x=2k and k=y. 
Hope that was helpful, have a good day! :))

Please help me will give brainlyest.

Answer:

x=24

Step-by-step explanation:

I think that its just a degree sign tbh

but because pc is a radius and so is pd their opposite angles are equal to each other.

so angle d and angle c are congruent

then because a triangles angles add up to equal 180 we do

180=x+54+x+54+x and solve for x

step 1 combine like terms x+x+x=3x 54+54=108

180=3x+108

step 2 subtract each side by 108

3x=72

step 3 divide each side by 3

x=24

hope this helps (:
