Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133 = 180
X = 47 degrees
The reason is because the total degrees in a triangle is 180 and 102 + 31 is equal to 133 degrees which then you take and subtract it from 180 which gives you 47 degrees.
