HELP QUICK!! WILL GIVE BRAINILIST<br> Find the value of x in the triangle shown below.
aev [14]

Answer:

58

Step-by-step explanation:

Since two of the sides are both 6.2, we know that this is an isosceles triangle. Thus, the two angles opposite of x are both equal (61 degrees).

The angles inside of a triangle always add up to 180, so now we have

180 = 61 + 61 + x

Solving for x, we get x = 180 - (61 + 61) = 180 - 122 = 58
