Answer:
58
Explanation:
We see that both sides around x are the same length, 6.2. This tells us our triangle is an isosceles triangle, which means two sides are the same lengths. This also tells us that two angles will be equal to each other.
The angle other than x and 61, will be equivalent to 61.
We also know that a triangle's angles equal 180. So,
180 - 61 = 119
119 - 61 = 58
x = 58
Sorry if my explaination isn't fully clear, it's hard to type it out and explain!
