Let us draw a picture to make the things more clear.
Attached is the image.
We have been given that

Therefore, we have

Now, in triangle bcd, we have

Now, in triangle acb, we have

Thus, ad is 15 cm.
<span>The basic idea is that you form a parallelogram with those two vectors as the two different side lengths
another way to see it: start at the tip of one vector and move in the same direction as the other vector (and the same length as the other vector)
</span><span>With any parallelogram, the adjacent angles are supplementary</span>
180-52-20= 108 degrees
Answer:
x=5
Step-by-step explanation:
I was working on this problem also.
Maybe my version will help, too.
You need to sketch f given the information you have.
f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)
f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.
f then slopes down to to x=5 where is has a minimum and then slopes up.
if im not wrong
