1. In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions The measure of RS = 5 and ST = 4. What is the length of segment TU? Show each step.

(a)

rs x st = tu  2

(b)

yes it is possible the formula is in part a, but we're given just the side rt and st, not rs, but not to worry we can get rs with subtraction. we can do 9-4=5 for rs. now we can plug in our values to find tu

5x4 = tu  2

simplify with algebra  

20 = tu

FINAL ANSWER

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
