<h2>It is an obtuse angle.</h2>

Step-by-step explanation:

Obtuse: An obtuse angle is an angle more than 90^\circ but less than 180^\circ.

Example : 110^\circ,135^\circetc.

Acute : An acute angle is an angle less than 90^\circ

Example : 30^\circ,45^\circ etc.

Straight : A straight angle is 180^\circ.

Right: A right angle is 90^\circ.

Since the angle is more than 90^\circ but less than 180^\circ . So, it is an obtuse angle.

The curved part of this figures is a semicircle.
vovangra [49]

First we join the two endpoints of the semicircle and that will be the diameter.

And to find the length of the diameter, we have to use distance formula, with one endpoint (3,2) and the other is (-4,-2) .

SO we get

Diameter = \sqrt{ {-4-3)^2 +(-2-2)^2 } = \sqrt{49+16} = \sqrt 65

Radius is half of diameter, so the radius is

Radius= \frac{ \sqrt{65}}{2}

Formula of area of circle is

Area = \pi r^2

So the area of semicircle is

=(1/2) \pi ( \frac{ \sqrt{65}}{2})^2 = 8.125 \pi \square \units

And the other figure is a triangle, with

Base = 3-(-4)=3+4=7 \\ height = 2-(-2) = 2+2 =4

Area = (1/2)*4*7= 14 square units

Therefore, total area is the sum of area of semicircle and area of triangle,

And we will get

Total \ area= 14 + 8.125 \pi \ units^2

Correct option is the third option .
