5 more than a number x is -4​
RSB [31]

Answer:

x = -9

Step-by-step explanation:

x = unknown

x+5 = -4

reverse it

-5 + -4 = -9

this will work from the fact that if x is equal to 5 more than -4 you would reverse it so that it is negative 4 - 5 which would be -9

Lim as x approaches 2pi/3 from the right of csc x, solve by substituting csc with sin
Zielflug [23.3K]
\bf csc(\theta)=\cfrac{1}{sin(\theta)}
\\\\
-------------------------------\\\\
\lim\limits_{x\to \frac{2\pi }{3}^+}~csc(x)\implies \lim\limits_{x\to \frac{2\pi }{3}^+}~\cfrac{1}{sin(x)}\implies \cfrac{1}{sin\left( \frac{2\pi }{3} \right)}\implies \cfrac{1}{\frac{\sqrt{3}}{2}}\implies \cfrac{\frac{1}{1}}{\frac{\sqrt{3}}{2}}

\bf -------------------------------\\\\
\cfrac{\frac{a}{b}}{\frac{c}{{{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{{ d}}}{c}\qquad thus\\\\
-------------------------------\\\\
\cfrac{1}{1}\cdot \cfrac{2}{\sqrt{3}}\implies \cfrac{1\cdot 2}{1\cdot \sqrt{3}}\implies \cfrac{2}{\sqrt{3}}
\\\\\\
\textit{and now, rationalizing the denominator, we get}\implies \cfrac{2\sqrt{3}}{3}

Does anyone know the answer??<br> You have to find x.
Irina18 [472]

Answer:x = 9.01

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle the hypotenuse of the right angle triangle is 17

With 35 degrees as the reference angle,

x represents the adjacent side of the right angle triangle.

The unlabelled side represents the opposite side of the right angle triangle.

θ = 35 degrees

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos 35 = x/11

x = 11 Cos 35 = 11 × 0.8192

x = 9.01
