Solve the Equation: Finding the Triangle Symbol in 41 + △ = 50

To determine the value of the triangle, we will solve the equation $41 + \triangle = 50$.

Let's solve it step by step:

• Step 1: Start with the equation: $41 + \triangle = 50$.
• Step 2: To isolate $\triangle$, subtract 41 from both sides:
• Step 3: $41 + \triangle - 41 = 50 - 41$.
• Step 4: This simplifies to $\triangle = 9$.

Therefore, the solution to the problem is $\triangle = 9$.
