Dana draws a triangle with one angle that has a measure of 40∘.

OLEGan [10]

Answer:

140°

Step-by-step explanation:

Given:

Dana draws a triangle with one angle that has a measure of 40∘.

Question asked:

What is the measure of the angle’s adjacent exterior angle?

Solution:

As we know:

Sum of the adjacent interior and exterior angles is 180°.

Interior angle = 40°

Adjacent exterior angle = ?

Interior angle + Adjacent exterior angle = 180°

40° + Adjacent exterior angle = 180°

By subtracting both sides by 40°

40° - 40° + Adjacent exterior angle = 180° - 40°

Adjacent exterior angle = 140°

Therefore, the measure of the angle’s adjacent exterior angle will be 140°.

Find the arc length of the partial circle..

Gala2k [10]

Answer:

The arc length of the partial circle is $6\pi\ units$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have a 3/4 of a circle

the circumference is equal to

$C=(\frac{3}{4})2\pi r$

$C=\frac{3}{2}\pi r$

we have

$r=4\ units$

substitute

$C=\frac{3}{2}\pi (4)$

$C=6\pi\ units$
