Answer:
X= 128º
Explanation:
A triangle is stated to have 180º. This means that since we know 2 sides of the triangle you can simply subtract them from one another.
Doing this you would get: 180 - 90 - 38 = 52º
Noticing that X is on a straight line, this would result in the fact that X is on a line of 180º.
Subtracting the angle we found in the triangle would result you with the answer of:
180 - 52 = 128º for the value of X
