What are all the exact solutions of -3tan^2(x)+1=0? Give your answer in radians.
goldenfox [79]
   
\displaystyle\\
 -3\tan^2x + 1 = 0\\\\
 -3\tan^2x = -1\\\\
\tan^2x =  \frac{-1}{-3} \\\\
\tan^2x =  \frac{1}{3} ~~~~~ \Big|~\sqrt{~~~} \\\\
\sqrt{\tan^2x} =  \sqrt{\frac{1}{3}} \\\\
\tan x = \Big| \frac{1}{ \sqrt{3} } \Big|\\\\
\tan x = \Big| \frac{\sqrt{3}}{ 3 } \Big|\\\\
\tan x =  \frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_1=  \frac{\pi}{6} + k\pi,~~k \in N \\\\  
\tan x =  -\frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_2=  \pi-\frac{\pi}{6} + k\pi = \frac{5\pi}{6} + k\pi,~~k \in N \\\\

What is the area of the figure?
vovikov84 [41]
Notice that the triangle is a right isosceles triangle, because the given angle measures are 45° and 90°, so the third angle measure is 180°-90°-45°=45°.

The length of the hypotenuse is 24 ft. Let the side lengths of the 2 equal sides be a.


By the Pythagorean theorem we have:

a^2+a^2=24^2

thus

2a^2=24^2

divide both sides by 2, and take the square root:

a= \frac{24}{ \sqrt{2} } = \frac{24 \sqrt{2} }{2}=12 \sqrt{2}


The area of the triangle is given by the formula:

(1/2)*side*side, so the area of the triangle is :


(1/2)*12 \sqrt{2}*12 \sqrt{2}=144 (square units)


Answer: 144 square units
