Find the direction angle for the given vector. Give your answer in degrees, rounded to one decimal place.
\[
\mathbf{v}=5 \mathbf{i}+14 \mathbf{j}
\]
Final Answer: The direction angle for the given vector is \(\boxed{70.3}\) degrees.
Step 1 :Given the vector \(\mathbf{v}=5 \mathbf{i}+14 \mathbf{j}\)
Step 2 :The direction angle of a vector can be found using the arctangent function (also known as the inverse tangent or atan). The direction angle is the angle between the vector and the positive x-axis.
Step 3 :In this case, we can use the formula atan(j/i) where i and j are the components of the vector. We need to convert the result from radians to degrees.
Step 4 :Let i = 5 and j = 14
Step 5 :Calculate the angle in radians: angle_radians = 1.2277723863741932
Step 6 :Convert the angle from radians to degrees: angle_degrees = 70.3461759419467
Step 7 :Final Answer: The direction angle for the given vector is \(\boxed{70.3}\) degrees.
