Well if the radius of the circle is 34.5 all you have to do to get the length of the diameter is double it (multiply by 2)
34.5•2=69
34.5+34.5=69
the diameter of the circle is 69
9514 1404 393
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
Answer:
The sum of this geometric series is 720.
Step-by-step explanation:
The sum of a infinite geometric series is given by the following formula:
Applying the data from the problem, we have:
The sum of this geometric series is 720.
350 because 25x10 is 250 and 20x5 is 100 so you add them and get 350
The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.
So therefore, we can say it's 9:6, so DE is 6.
