To solve this problem you must apply the proccedure shown below:

1. You can use the Law of Sines to calculate the missing angle. You have that:

\frac{a}{SinA}=\frac{b}{SinB}

Where:

a=22\\ b=12\\ A=75degrees\\ B=x

2. Substitute values and solve for x, as following:

\frac{22}{Sin(75)}= \frac{12}{Sin(x)}

Sin(x)=\frac{(12)(Sin(75))}{22} \\ x=arcsin\frac{(12)(Sin(75))}{22}\\ x=31.8degreees

Therefore, the answer is: x=31.8degrees

Find the common ratio of the geometric sequence: -320,80,-20,5
Flauer [41]

Answer:

-1/4 if you prefer the answer written as a fraction.

-0.25 is you prefer the answer written as a decimal.

Step-by-step explanation:

Common ratio of a geometric sequence can be found by doing term divided by previous term.

That is you could do:

80/-320

or

-20/80

or

5/-20

If all these ratios are not equal, it isn't a geometric sequence and does not have a common ratio.

Let's see what these reduce to:

80/-320=1/-4 =-1/4 or -0.25

-20/80=-1/4 or -0.25

5/-20=1/-4=-1/4 or -0.25

So the common ratio is -0.25 or yo you can write it as -1/4.
