Answer:
140°
Step-by-step explanation:
<3 = 40 because they are vertical angles
<3 +<4 = 180 because they are same side interior angles
40 + <4 = 180
Subtract 40 from each side
40-40 + <4 = 180-40
<4 = 140
If the radius of the circle is 4 than the area would be 50.27.
If you are saying that 4 is the diameter, than divide that by 2 to get the radius which is 2. The area for this would be 12.57.
I don’t know which one you mean but hope this helps :))
