Answer:
Measure of side YX is 22 units.
Step-by-step explanation:
Since ΔVWZ ~ ΔXWY, their corresponding sides will be in the same ratio.
By substituting the values given in the picture in the ratio,
By cross multiplication,
2(3x - 9) = 3(x + 8)
6x - 18 = 3x + 24
(6x -18) + 18 = 3x + 24 + 18
6x - 3x = (3x + 42) - 3x
6x - 3x = 42
3x = 42
x =
x = 14
m(YX) = x + 8
= 14 + 8
= 22
Therefore, measure of side YX is 22 units.
Answer:
About 18.5 feet
Step-by-step explanation:
The circumference of a circle can be found using:
c=d
We know d, or diameter is 6, so we can plug that it
c=6
Multiply
c=18.8495559215
Rounded to the nearest hundreth
c=18.50 feet
The circumference is about 18.5 feet
