Answer:
x = 16
Step-by-step explanation:
Given a tangent and a secant from an external point to a circle, then
The product of the external part and the whole of the secant is equal to the square of the tangent, that is
9(9 + x) = 15²
9(9 + x) = 225 ( divide both sides by 9 )
9 + x = 25 ( subtract 9 from both sides )
x = 16
34.9 because its 90 angle so you subtract the 55.1
They would cost $8.75. If you take out 30% from the original price, that is how much they would be.
Add 7 to each side of the inequality.
w < 28.
