vec(u)=(5,3) Find the direction angle of vec(u). Enter your answer as an angle in degrees between 0^(@) and 360^(@) rounded to the nearest hundredth. theta=◻" 。 "

Step 1: Formula for direction angle: To find the direction angle of the vector vec(u) = (5,3), we need to use the arctangent function, which gives us the angle whose tangent is the ratio of the y-coordinate to the x-coordinate of the vector. The formula to find the direction angle θ is: θ = arctan(y/x) where x and y are the x-coordinate and y-coordinate of the vector, respectively.Step 2: Plugging in the coordinates: Now we will plug in the values of the coordinates of vec(u) into the formula: θ = arctan(3/5)Step 3: Calculating the arctangent: Using a calculator, we find the arctangent of 3/5: θ ≈ arctan(0.6) θ ≈ 30.96 degreesStep 4: Determining the direction angle: Since the vector vec(u) is in the first quadrant (both x and y are positive), the direction angle θ is already between 0° and 360°. Therefore, we do not need to adjust the angle further.

Step $1$ : Formula for direction angle: To find the direction angle of the vector $\vec{u} = (5,3)$ , we need to use the arctangent function, which gives us the angle whose tangent is the ratio of the y-coordinate to the x-coordinate of the vector. The formula to find the direction angle $\theta$ is: $\newline$ $\theta = \arctan(\frac{y}{x})$ $\newline$ where $x$ and $y$ are the x-coordinate and y-coordinate of the vector, respectively.
Step $2$ : Plugging in the coordinates: Now we will plug in the values of the coordinates of $\vec{u}$ into the formula: $\theta = \arctan(\frac{3}{5})$
Step $3$ : Calculating the arctangent: Using a calculator, we find the arctangent of $\frac{3}{5}$ : $\newline$ $\theta \approx \arctan(0.6)$ $\newline$ $\theta \approx 30.96$ degrees
Step $4$ : Determining the direction angle: Since the vector $\vec{u}$ is in the first quadrant (both $x$ and $y$ are positive), the direction angle $\theta$ is already between $0^\circ$ and $360^\circ$ . Therefore, we do not need to adjust the angle further.
