Answer:
sinx=cosy
sinx=sin(90−y)
x=90−y
x+y=90
Step-by-step explanation:
Answer:
Step-by-step explanation:
2-(-1\8)±-7\4 then
2 plus 1\8 plus -7\4
2 plus 1\8 plus -14\8
2 -13\8
2= 16/8
3\8?
The answer is: A. 20.3
The explanation is shown below:
1. By definition, the sum of the length of the strings (The length of the blue segment and the length of the red segment) is equal to the length of the major axis (The black segment).
2. Based on this, you can write the following expression, where
is the length of the blue segment:

3. Now, you must solve for
, as following:


4. Therefore, the answer is the option A.
2 = z - 14
+14 +14
16 = z
First of all, remember that 100% is one whole thing.
Then.look at the problem, and see that 90 is three times 30.
-- 90 is 300% <em><u>of</u></em> an entire 30 .
-- To go from 30 to 90, you have to increase the 30 <em>by</em> 200% of itself.
