Question

Help I'm stuck on this one. Explain

Answer 1

20⁰

Explanation:

As the two sides are equal , this two angles are 80⁰. Last angle is x

By using angle sum property

x + 80 + 80 = 180

x = 180 - 160

x = 20⁰

Answer 2

It is an isosceles triangle which means two sides are the same and when two sides are the same then the two angles are the same. The bottom one is
80 degrees so the other angle equals to 80 degrees
Add both 80 degrees angle
80+80= 160 In a triangle all the angles equal to 180, so now you subtract
180-160 = 20
The angles are 80, 80 ,20
The 20 is on top and the two 80 are on the bottom
