Convert the angle \theta=\dfrac{8\pi}{9}θ=

Olegator [25]

Answer:

160°

Step-by-step explanation:

-Given the angle in radians as $\theta=\dfrac{8\pi}{9}\ rad$

-We know that $1 \ rad=\frac{180}{\pi}\textdegree$

-Let our angle theta be X

#We therefore equate and cross multiply:

$1\ rad=\frac{180}{\pi}\\\\\frac{8\pi}{9}=x\\\\\therefore X=\frac{180}{\pi}\times \frac{8\pi}{9}\\\\=160\textdegree$

Hence, angle θ is 160°

If three times a number added to 8 is divided by the number plus 7, the result is four thirds. Find the number.

Marina86 [1]

9514 1404 393

Answer:

4/5

Step-by-step explanation:

The wording is ambiguous, as it often is when math expressions are described in English. We assume you intend ...

$\dfrac{3n+8}{n+7}=\dfrac{4}{3}\\\\3(3n+8)=4(n+7)\qquad\text{multiply by $3(n+7)$}\\\\9n+24=4n+28\qquad\text{eliminate parentheses}\\\\5n=4\qquad\text{subtract $4n+24$}\\\\\boxed{n=\dfrac{4}{5}}\qquad\text{divide by 5}$

The number is 4/5.
