Given:

Consider the below figure attached with this question.

m\angle 3=(x+30)^\circ and m\angle 4=(2x-80)^\circ.

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

m\angle 3=m\angle 4

(x+30)^\circ=(2x-80)^\circ

x+30=2x-80

x-2x=-30-80

-x=-110

x=110

Now,

m\angle 3=(110+30)^\circ

m\angle 3=140^\circ

Therefore, the measure of angle 3 is 140 degrees.

The circle below is centered at the point (4,1) and has a radius of length 2. What is it’s equation?
vekshin1

Answer:

Option B:

(x-4)^2+(y-1)^2 = 4

Step-by-step explanation:

Given

Centre = (h,k) = (4,1)

Radius = r = 2

The standard equation of circle is:

(x-h)^2+(y-k)^2=r^2

Putting the values of h,k and r

(x-4)^2+(y-1)^2 = (2)^2\\(x-4)^2+(y-1)^2 = 4

Hence, the correct option is option B

(x-4)^2+(y-1)^2 = 4
