Math Problem Statement
Solution
The diagram shows a triangle with an angle of and two angles marked as equal by the tick marks. This indicates that the triangle is isosceles, where two sides are of equal length and, therefore, their opposite angles are equal.
To solve for :
-
Sum of angles in a triangle: The sum of the internal angles of any triangle is always .
-
Let the two equal angles be : Since it's an isosceles triangle, the two base angles are equal.
-
Set up the equation: Simplifying: Subtract 32 from both sides: Divide by 2:
So, the value of is .
