In the diagram, point P is a point of tangency. Find the radius r of circle O.​
vlabodo [156]

Answer:

r = 12

Step-by-step explanation:

From the figure attached,

QP is a tangent to the circle O at the point P.

Therefore, by the property of tangency,

OP ⊥ QP

By applying Pythagoras theorem In right triangle QPO,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

(OQ)² = (OP)² + (PQ)²

(25 + r)² = (35)² + r²

625 + r² + 50r = 1225 + r²

50r = 1225 - 625

50r = 600

r = 12

Therefore, r = 12 units is the answer.

<h3>Which of the following expressions could represent how much Leila pays in total for the model?</h3>

The price of the model is  x

Now we are given that she also has to pay a 7  tax.

Amount of tax =7 % x

=\frac{7}{100} x

the Total cost=x+\frac{7}{100} x
