Central= 127 Radius= 7. What is the length of the indicated arc (x)

tia_tia [17]

Given:

$\begin{gathered} \theta\text{ = 127} \\ r\text{ = 7 mm} \end{gathered}$

Required:

Length of an arc x.

Explanation:

Length of an arc is given as,

$Length\text{ of an arc =}\frac{\theta}{360}\times2\pi\text{r}$

Length of an arc is calculated as,

$\begin{gathered} Length\text{ of an arc = }\frac{127}{360}\times2\times3.14\times7 \\ Length\text{ of an arc = 0.3528 }\times2\times3.14\times7 \\ Length\text{ of an arc = 15.5091 mm} \\ \end{gathered}$

Answer:

Thus the value of the length of an arc is 15.5091 mm

Triangles DEF and D'E'F' are shown on the coordinate plane below:

Lorico [155]

The <em><u>correct answer</u></em> is:

90° clockwise

Explanation:

Comparing the image points to the pre-image points, we can see that in every ordered pair, x and y have been switched and x has been negated. Algebraically, this means (x, y)→(y, -x).

This is the same mapping that a 90° clockwise rotation performs, so that is our answer.
