The values would be

sin2x = -3/5

cos2x = -4/5

tan2x = 3/4

What are double angles in trigonometry?

The double angle formulas are used to find the values of double angles of trigonometric functions using their single angle values. For example, the value of cos 30° can be used to find the value of cos 60°. Also, the double-angle formulas can be used to derive the triple-angle formulas.

Given: tanx = -3

Now as we know,

                  sin2x=\frac{2tanx}{1+tan^2x}\\\\sin2x=\frac{2(-3)}{1+(-3)^2}\\\\sin2x=\frac{-6}{10}\\\\sin2x=\frac{-3}{5}

Now

               cos2x=\frac{1-tan^2x}{1+tan^2x}\\\\cos2x=\frac{1-(-3)^2}{1+(-3)^2}\\\\cos2x=\frac{1-9}{1+9}\\\\cos2x=\frac{-8}{10}\\\\cos2x=\frac{-4}{5}

And similarly, we can find the value of tan2x, as

                  tan2x = sin2x/cos2x

                             = (-3/5)/(-4/5)

                             = 3/4

Hence,

The values would be

sin2x = -3/5

cos2x = -4/5

tan2x = 3/4

In the parallelogram below,<br> y = [?]<br> 5y-20<br> 2y+25<br> PLEASE HELP
Firdavs [7]
If I remember correctly parallelograms have two pairs of parallel lines equal to each other

So 5y-20=2y+25

Solve for y

3y=45

y=15

The answer is y=15

80 students took an algebra exam and 75 past it in simplest form what fraction of students did not pass the exam
mafiozo [28]

Answer:

1/16

Step-by-step explanation:

75 of the 80 pass

80-75 = 5

That means 5 did not pass

Fraction that did not pass = people that did not pass/ total

                                           = 5/80

divide the top and bottom by 5

                                            =1/ 16
