According to the picture, angles 1 and 2 have the same measure because they are corresponding angles. Make equal both expressions for 1 and 2 and find x.

x is 3/2. Replace this value in both expression to find the measure of each angle.

The measure of these angles is 47°
The magnitude of the vector is

the component form is
<2,5>
A = 143 m^2 because the height is 11 m and the width is 13 m if you add 9+4.
