Answer:

x = - 8.

Step-by-step explanation:

Given : 16 = -2x - 1

To find : Solve for x.

Solution : We have given

16 = -2x - 1

On adding both sides by 1

16 + 1 = -2x .

17 = - 2x

On dividing both sides by -2.

x = - 8. 5

If we rounded it it would be - 8 .

Therefore, x = - 8.

I tend to flip so x is on the left, so:

-2x - 1 = 16

-2x = 17

x = -17/2, which is -8.5

Rounding up, your answer would be x = -8 !

Tan 45°. tan² 30° tan 60° <br>slove it

makvit [3.9K]

Answer:

$\frac{\sqrt{3} }{3} or \frac{1}{\sqrt{3} }$

Step-by-step explanation:

We can break the problem into three parts,

tan45 = sin(45)/cos(45)= $\frac{\frac{\sqrt{2}}{2} }{\frac{\sqrt{2}}{2} } =1$

$tan^{2}30 =(tan30))^{2}=(sin30/cos30)^2=((1/2)/(\sqrt{3}/2))^2 =(1/\sqrt{3})^2$

$tan60=sin60/cos60=\frac{\sqrt{3}/2 }{1/2} =\sqrt{3}$

Then, $tan45*tan^230*tan60=1*(1/sqrt(3))^2*sqrt(3)=1/sqrt(3)=sqrt(3)/3$

Therefore, the solution is sqrt(3)/3
