Minimum angle of deviation of a glass prism is equal to angle of prism. What is angle of prism?

Explanation

To find the angle of the prism when the minimum angle of deviation (Δ) is equal to the angle of the prism (A), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Relationship**:
We know that for a prism, when the minimum angle of deviation (Δ) is equal to the angle of the prism (A), we can express this relationship mathematically. The relationship is given by:
\[
A + Δ = I + E
