Question

Solve for x
I need help, I don’t really understand the work

Answer 1

• x = 25°

Explanation:

From the given figure It is isosceles triangle. Here 2x+ 10 and 60° are the opposite angles.

The two angles of an isosceles triangle, opposite to equal sides, are equal in measure.

`\sf 2x + 10 = 60`

`\sf 2x = 60 - 10`

`\sf 2x = 50`

Divide both sides by 2 ,

`\sf x = 25°`

Answer 2

x = 25

Explanation:

Since the sides are congruent, the angles are congruent.

2x + 10 = 60

2x = 50

x = 25
