A) 7 pi / square root 10 = 7(3.14)/3.162277660 = 6.95
b) square root 75 - square root 74 = 8.660254038-8.602325267=0.058
c) square root 37 - square root 26 = 6.082762530-5.099019514=0.98
s) 3 square root 5 - square root 20 / square root 2 =
3(2.236067978) - 4.472135955/1.414213562=6.708203934-3.162277661=
3.546

Which of the following are solutions to 2tanx/1-tan^2x=sqrt 3?

Tanya [424]

Answer:

A, D

Step-by-step explanation:

$(\frac{2tanx}{1-tan^{2}x}) =\sqrt{3}$ (1)

Assume that tan x = y. Replace this into the equation (1), we have:

+) $\frac{2y}{1-y^{2} } =\sqrt{3}$

=> 2y = $\sqrt{3} . (1 -y^{2} ) =- \sqrt{3} .y^{2} + \sqrt{3}$

=> $\sqrt{3} .y^{2} + 2y - \sqrt{3} = 0$

=> $\sqrt{3} . y^{2} - 1.y + 3.y - \sqrt{3} =0$

=> $(\sqrt{3} . y.y - 1.y) + (\sqrt{3}.\sqrt{3} .y - \sqrt{3}) =0$

=> $y.(\sqrt{3} y - 1) + \sqrt{3} (\sqrt{3} y - 1) = 0$

=> $(y + \sqrt{3} ).(\sqrt{3} .y -1)=0$

=> $y + \sqrt{3} = 0$ or $\sqrt{3} y -1 =0$

If $y + \sqrt{3} = 0$

=> y = - √3

=> tan x = - √3

=> x = $\frac{2\pi }{3}$ + n. $\pi$ with n is an integral

If $\sqrt{3} y -1 =0$

=> y = 1/√3

=> tan x = 1/√3

=> x = $\frac{\pi }{6} + n.\pi$ n is an integral

So that A, D are answers.

Does every acute triangle have 3 congruent sides?

Gemiola [76]

No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.
