.
he bought 34 pencils which I suppose aren't already sharpened
so if he sharpens 16 of them just subtract 16 from 34 (34-16) which equals 18
so the ratio would be 16:18
but if u need to simplify it would be 8:9
Answer:

Step-by-step explanation:
First we need to set up an equation in order to find the value of x. We know that the sum of these angles are 180°

Now we can plug in our value for x into each of the angle's equations

ST^2 = 7 ( 7 + 23) ( I think its called the tangent/secant length theorem)
ST^2 = 210
ST = sqrt 210 = 14.49 to nearest hundredth.
