Step-by-step explanation:
Concept:
Here, we need to know the concept of an isosceles triangle.
An isosceles triangle is a triangle that has any two of its sides equal to each other. The corresponding angles of the equal sides are also equal.
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
Let x be m∠EGF
2x + 50 = 180 ⇒ Write the equation
2x + 50 - 50 = 180 - 50 ⇒ Subtract 50 on both sides
2x = 130 ⇒ Simplify
2x / 2 = 130 / 2 ⇒ Divide 2 on both sides
x = 65 ⇒ Simplify
Hope this helps!! :)
