Answer:
x=117
Explanation:
since there is 2 angles that they already give you the measurements with. you try to solve the 101 angle and subtract 180-101= 79. this is the angle beside 101. since a triangle is equal to 180 degrees; you add the 38 and 79 which equals 117. you subtract 180-117=63. That is the other angle on the inside of the triangle.
