The question from the image asks:

"Find the angle between the radius and the tangent to the curve, and also find the slope of the tangent at the indicated point."

It seems to be related to a problem involving the geometry of curves, likely in polar coordinates or with parametric equations where a radius vector from the origin and a tangent to a curve meet at some point. To solve this:

### 1. **Find the Angle Between Radius and Tangent:**
For a curve (especially a circle or another curve in polar form), the angle \(\theta\) between the radius and the tangent can be found using geometric or calculus principles.

- **For a circle**, this angle is always \(90^\circ\) because the radius is perpendicular to the tangent at any point on the circle.
  
- **For other curves**, you use the derivative (slope of the tangent) and the slope of the radius to find the angle using the following formula:
  \[
  \tan(\alpha) = \left| \frac{m_t - m_r}{1 + m_t m_r} \right|
  \]
  where \(m_t\) is the slope of the tangent and \(m_r\) is the slope of the radius.

### 2. **Find the Slope of the Tangent:**
The slope of the tangent to the curve at a given point is found using differentiation:
\[
\text{slope of tangent} = \frac{dy}{dx}
\]
If the curve is given explicitly as \(y = f(x)\), this is done by differentiating \(y\) with respect to \(x\).

For a parametric curve, the slope is given by:
\[
\frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}
\]
where \(x\) and \(y\) are functions of a parameter \(t\).

For a polar curve \(r = f(\theta)\), the slope of the tangent is given by:
\[
\frac{dy}{dx} = \frac{r'(\theta)\sin(\theta) + r(\theta)\cos(\theta)}{r'(\theta)\cos(\theta) - r(\theta)\sin(\theta)}
\]
where \(r'(\theta)\) is the derivative of \(r\) with respect to \(\theta\).

To provide the most specific answer, could you clarify the exact type of curve or provide additional information about the point or equation of the curve?

Let me know if you'd like more details! Here are some related questions you can consider:

1. What is the equation of the curve in this case?
2. Is the curve given in polar or parametric form?
3. Is the indicated point clearly given, or is it implied by the curve?
4. Are we dealing with a specific type of curve (e.g., circle, parabola, ellipse)?
5. What are the coordinates or parametric values of the point where the tangent needs to be calculated?

**Tip:** The tangent to a curve at a given point is always perpendicular to the radius if the curve is circular. For other curves, calculus is needed to find the slope.

Find the angle between the radius and tangent to the curve, and also find the slope of the tangent at the indicated point.
