Solve the Equation: Finding the Value in 5 + △ = 10

Determine the numerical value of the ${\triangle}$

$5+{\triangle}=10$

To solve the problem, we will determine the value of $\triangle$ in the equation $5 + \triangle = 10$.

Here are the steps:

• Step 1: Write down the original equation:

$5 + \triangle = 10$

• Step 2: Isolate $\triangle$ by subtracting $5$ from both sides of the equation:

$\triangle = 10 - 5$

• Step 3: Calculate the result:

$\triangle = 5$

Thus, the numerical value of the triangle symbol is $5$.

Therefore, the solution to the problem is $5$.
