2x - y = 0
2x = y
3x - 2(2x) = -3
3x - 4x = -3
-x = -3
x = 3
2(3) = y
6 = y
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!
Given:
Two vectors are:


To find:
The projection of u onto v.
Solution:
Magnitude of a vector
is:

Dot product of two vector
and
is:

Formula for projection of u onto v is:




On further simplification, we get



Therefore, the projection of u onto v is
.
Answer:
x = -2 and x = 5/4
Step-by-step explanation:
The image below shows step-by-step on how to solve it.
Hope this helps! :)
The solution would
be like this for this specific problem:
(cos^2x-1)/cosx+1
cos^2x-1= (cosx+1)(cosx-1)
cosx-1
