What is the value of X?
svet-max [94.6K]

Answer: 71 degrees.

Step-by-step explanation:

Due to the triangle being isosceles (Two sides are equal), we can assume that the angles will also be equal.

You can take 180 (The total of a triangle) and subtract by the known degree

180 - 38 = 142

Now we divide 142 by two, ONLY because this is case; both angles will be the same degree.

142 / 2 = 71

Therefore; x = 71
