Question

**Transcription for Educational Website**

**Problem 1:**

Find the values of θ, r, and φ given the equation:

\[ 1.5 \cos \theta + 2.5 \sin \theta = 2.8 \]

**Formulas:**

- \( r = \sqrt{a^2 + b^2} = \)

- \( \phi = \text{atan2}(a, b) = \)

- \( \theta = \)

**Explanation:**

- **\( r \) Formula:** This represents the magnitude, calculated using the Pythagorean theorem for \( a \) and \( b \).

- **\( \phi \) Formula:** This is the angle whose tangent is the quotient of two specified numbers, calculated using the `atan2` function which considers the signs of both variables to determine the quadrant of the angle.

Fill in the blanks using the given equation and solve for the variables.
