Answer:

2. chord theorem; t = 10.5

3. chord theorem; x = 5

Step-by-step explanation:

For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.

2. 20t = 10·21

t = 210/20 . . . . divide by 20

t = 10.5 . . . . . . . simplify

3. 10(x +4) = 15(x +1)

10x +40 = 15x +15 . . . . . eliminate parentheses

25 = 5x . . . . . . . . . . . . . subtract 10x+15

5 = x . . . . . . . divide by 5
