Always because the sum of x and y is 180 degrees. If x and y are right angles, then x and y are supplementary angles. Never because the sum of x and y has to be 90 degrees. If x and y are complementary angles, then y is a right angle.
Answer:
1/10
when you do the LCM you get 70
divide each fraction by 70 and you will get the least to be a tenth
Answer:
Step-by-step explanation:
if (x,y) is any point on unit circle then
x²+y²=1²
x²+y²=1
(3/4)²+y²=1
9/16+y²=1
y²=1-9/16=(16-9)/16=7/16
y=±√7/16
We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

We know that there is <span>a water station that is twice as far from the starting line as from the finish line, then:
</span>

So:

∴

and

<span>Finally, the distance of the runner from the finish line is:
</span>
