Answer:
x = 18√3
Step-by-step explanation:
From the picture attached,
In a right triangle,
Measure of one angle = 30°
Measure of adjacent side of the angle = 9 units
We have to find the measure of Hypotenuse from the given properties.
By cosine rule,
cos(30°) =
Therefore, measure of Hypotenuse is 18√3 units.
PART A
The geometric sequence is defined by the equation
To find the first three terms, we put n=1,2,3
When n=1,
When n=2,
When n=3
The first three terms are,
PART B
The common ratio can be found using any two consecutive terms.
The common ratio is given by,
PART C
To find
We substitute n=11 into the equation of the geometric sequence.
This implies that,
