Answer:
Draw a picture and you'll see a right triangle with sides = 7 and 24 and hypotenuse = r (the cricle's radius). By the Pythagorean Theorem:
r2 = 72 + 242
Area = pi·r2
Step-by-step explanation:
Hey there! :D
Pay attention to the given angles.
We know that a circle is equal to 360 degrees.
We know two angles, and the other 2 are the same measure.
170+44= 214
Subtract that from 360, since that is what the circle equals.
360-214= 146
Divide that by two, since there are 2 equal angles left.
146/2= 73
<DOB= 73 degrees.
You were correct, so good work!
I hope this helps!
