Answer:
Ax =7 cm
Explanation:
Analysis:
Let A be the vector of rectangular components Ax and Ay:
Where:
Ay=7 cm : The The y-component of vector A-component of vector A
α =45 : Angle of A with the positive x-axis
Ax : The x-component of vector A
Because Ax and Ay are the components of a right triangle we apply the following formula:
[tex]tan\alpha =\frac{A_{y} }{A_{x} }[/tex]
[tex]tan45=\frac{7}{A_{x} }[/tex]
[tex]A_{x} =\frac{7}{tan45}[/tex]
Ax =7 cm
