Answer:
x = 79
Explanation:
To find the value of x we first need to find the missing angle of the triangle in the image.
- The sum of interior angles in a triangle is equal to 180°.
101 + 29 + missing angle = 180
130 + missing side = 180
- subtract 130 from both sides
missing side = 50
Now, the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
So the value of x:
29 + 50 = 79
