An angle measures 4.3 radians To the nearest degree, what is the measure of the angle? degrees
Veseljchak [2.6K]
Well, we know there are 180° in π radians, how many degrees are there in 4.3 radians?

\bf \begin{array}{ccll}
de grees&radians\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
180&\pi \\
d&4.3
\end{array}\implies \cfrac{180}{d}=\cfrac{\pi }{4.3}\implies \cfrac{180\cdot 4.3}{\pi }=d

Yuliya22 [10]

Answer:

D. y - y_0 = m(x - x_0).

Step-by-step explanation:

The equation of a line can be written in the point-slope form if we know the the coordinates of a point the line passes through which is (x_0, y_0). And if we also know the slope = m of the line.

Therefore, the point-slope equation is given as:

y - y_0 = m(x - x_0)
