Solve the Equation: Triangle Symbol - 8 = 90

Determine the numerical value of the triangle:

$\triangle-8=90$

To solve this problem, we'll follow these steps:

• Step 1: Add 8 to both sides of the equation $\triangle - 8 = 90$.
• Step 2: Simplify to determine the value of $\triangle$.

Now, let's work through each step:

Step 1: Add 8 to both sides of the equation:
$\triangle - 8 + 8 = 90 + 8$

Step 2: Simplify the equation:
$\triangle = 98$

This means the value of the triangle ($\triangle$) that satisfies the equation is $98$.

Therefore, the solution to the problem is $98$.
