Pls help me with this question and explain how you got the answer

-87

Step-by-step explanation:

So, first to find x you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and x lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find x. The same thing can be done for y. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get y. So, let's do that.

180-121=x

59=x

180-34=y

146=y

Once you've done that you can easily subtract the two and get your answer.

x-y

substitute the answer for the variables and get

59-146

and then your answer is

-87

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
