Question

Find the value of xxx in the triangle shown below.

Answer 1

x = 50°

Explanation:

x = (180 - 80) ÷ 2

= 100 ÷ 2

= 50°

Answer 2

Answer: 50°

Explanation:

First, we can see that this is an isosceles triangle! That means the two angles at the bottom are the same.

A triangle's angles all equal 180 when added together, so knowing this, lets work backwards

180 - 80 = 100

Now, the two angles at the bottom are the same, so lets just divide 100 by 2, and our answer is 50!

Hope this helps :)
