Step-by-step explanation:
If AB is a tangent then ∠ ABC = 90° and Δ ABC is right
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides.
15 is the longest side and 15² = 225
9² + 12² = 81 + 144 = 225
Thus Δ ABC is a right triangle at B
Thus AB is a tangent to the circle at B

Answer:x=29
Step-by-step explanation:
You want to add all the like terms together so in this case 2x and x
29,30,20,8
3x=87
Divide 3 by both sides
X=29
Answer:
$98.75
Step-by-step explanation:
50×75÷100 = 37.5 + 50 = 87.5
87.5 × 30 ÷ 100 = 26.5
87.5 - 26.5 = 61.25
87.5 + 61.25 = 148.75
148.75 - 50 = 98.75
