Question

How do I find the value in x shown in the picture?

Answer 1

80°

Explanation:

x = (180° - 2x50°) = 180° - 100° = 80°

Answer 2

The missing angle is
`80` degrees.

Explanation:

If this is an isoceles triangle, it means that the two angle on the bottom left and right are the same. Since a triangle's angles add up to 180 degrees, we can create an equation :

`50+50+x=180`

`100+x=180`

`x=80`
