We have some number x that we do two things to it in this exact order: divide by 3, add 8.

To isolate x or get it all by itself, we have to undo what is happening to x. We follow the order mentioned above in reverse so that we undo everything properly. Undo the "add 8" by subtracting 8 from both sides. Then you undo the "divide by 3" by multiplying both sides by 3. Check out the attached image for details and the steps on how to solve. The final answer is x = 18

How do u find length of a obtuse angle

wolverine [178]

Answer:

An obtuse triangle is a triangle that has a single obtuse angle, which is an angle that measures more than 90 degrees and less than 180 degrees. Obtuse triangles, also referred to as oblique triangles, can be recognized by their having a single significantly larger angle and two smaller angles. Since every triangle has a measurement of 180 degrees, a triangle can only have one obtuse angle. You can calculate an obtuse triangle using the lengths of the triangle's sides.

Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4. Adding the squares together results in 13.

Square the length of the side opposite the obtuse angle. For the example, if the length is 4, then squaring it results in 16.

Find the inverse of each function.

Novosadov [1.4K]

as you should know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

$\stackrel{f(x)}{y}=\sqrt{x}-5\implies \stackrel{\textit{quick switcheroo}}{x=\sqrt{y}-5}\implies x+5=\sqrt{y} \implies (x+5)^2=y \\\\\\ \stackrel{F~O~I~L}{(x+5)(x+5)}=y\implies x^2+10x+25=\stackrel{f^{-1}(x)}{y}$
