The components of vector A are Ax and Ay (both positive), and the angle that it makes with respect to the positive x axis is θ.
DIA [1.3K]

Answer:

a) \theta = tan^{-1} (\frac{11}{11})= tan^{-1} (1)=45 degrees

b) \theta = tan^{-1} (\frac{11}{19})= tan^{-1} (0.579)=30.07 degrees

c) \theta = tan^{-1} (\frac{19}{11})= 59.93 degrees

Explanation:

If we have a vector A= (A_x ,A_y) in a two dimensional space. The angle respect the x axis can be founded from the following expression:

tan (\theta)= \frac{A_y}{A_x}

And then the angle is given by:

\theta = tan^{-1} (\frac{A_y}{A_x})

Part a

Ax = 11 m and Ay = 11 m

For this case the angle would be:

\theta = tan^{-1} (\frac{11}{11})= tan^{-1} (1)=45 degrees

Part b

Ax = 19 m and Ay = 11 m

For this case the angle would be:

\theta = tan^{-1} (\frac{11}{19})= tan^{-1} (0.579)=30.07 degrees

Part c

Ax = 11 m and Ay = 19 m

For this case the angle would be:

\theta = tan^{-1} (\frac{19}{11})= 59.93 degrees
