Answer:
Kenjii can use 13.19 kilowatt-hour.
Step-by-step explanation:
Giving the following information:
Kenji's electricity bill costs $21.56 per month plus $2.46 per kilowatt-hour.
<u>First, we will structure the total cost formula:</u>
Total cost= 21.56 + 2.46*x
x= kilowatt-hour
54= 21.56 + 2.46x
32.44= 2.46x
13.19= x
Kenjii can use 13.19 kilowatt-hour.
C=2πr=2(9)π=18π......

Answer: x = 150°
Step-by-step explanation:
The tangent intersects the circle's radius at a 90° angle, so ∠OAC = ∠OBC = 90°.
AOBC is a quadrilateral and we know that sum of interior angles of quadrilateral equals to 360°.
Now,
∠OAC + ∠OBC + ∠AOB + ∠ACB = 360°
90° + 90° + x + 30° = 360°
210° + x = 360°
x = 360° - 210°
x = 150°
