Answer:
The answer for this question is A. (4,-4)
9514 1404 393
Answer:
49°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠A +∠B +∠C = 180
(x +32) +(x +41) +(3x +22) = 180 . . . . angles assumed to be in degrees
5x +95 = 180
5x = 85
x = 17
x +32 = 49 . . . . measure of ∠A
Answer:
![v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]](https://tex.z-dn.net/?f=v%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1i%5C%5C0j%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
We know that the given unit vector is in the direction of the x-axis.
Remember that an unit vector is a vector which magnitude is the unit, that's why is called like that.
So, the given unit vector can be written as
, where
indicates the horziontal coordinate and
indicates the vertical coordinate.
As a vertical or colum vector would be
![v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]](https://tex.z-dn.net/?f=v%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1i%5C%5C0j%5Cend%7Barray%7D%5Cright%5D)
Therefore, the answer is
![v=\left[\begin{array}{ccc}1i\\0j\end{array}\right]](https://tex.z-dn.net/?f=v%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1i%5C%5C0j%5Cend%7Barray%7D%5Cright%5D)
