Answer:
121
Step-by-step explanation:
31+90 = 121
180 - 121 = 59
180 - 59 = 121
Answer:
the answer is 12.24 .
Step-by-step explanation:
that answer is right is because when you add of those you get 530 , then you divide by how many numbers there are which is 7 , which equals to 75.7 . when you get that number ( 75.7) you subtract that number to 65,90,85,70,70,95, and 55 . when you get the total of all of those you add those . which is 10.7, 14.3 , 9.3 , 5.7 , 5.7 , 19.3 , and 20.7 . from adding those you get 85.7. you divide by 7 and get 12.24 . hope this helps :) .
Answer: Option B, Option C, Option E
Step-by-step explanation:
The options written correctly, are:

For this exercise you need to use the following Inverse Trigonometric Functions:

When you have a Right triangle (a triangle that has an angle that measures 90 degrees) and you know that lenght of two sides, you can use the Inverse Trigonometric Functions to find the measure of an angle
:

Therefore, the conclusion is that the angles "x" and "y" can be found with these equations:

The ratio of the areas is the one-to-one measure squared. In order to find the ratio of their volumes, which is a cubed measure, we have to find the one-to-one and them cube it. The square root of 1/16 is 1/4. Now if we cube 1/4 to get the volume, it will be 1/64.
