Answer:
X = 71°
Step-by-step explanation:
Fierst of all that's an isosceles Triangle.
Isosceles triangle are triangles that have two sides and two angles equal .
To determine mine x, we are given one angle to be 38°.
Total angle in a triangle= 180
In that triangle
X+X+38= 180
The other angle is equal to X .
2X = 180-38
2X = 142
X =142/2
X = 71°
