Answer: x=29
Explanation:
In a triangle, the sum of the measures of all angles is 180 degrees.
Therefore, we can add up all the angles in this triangle, setting them equal to 180:
65+57+2x=180
Using the equation above, solve for x:
Simplify:
122+2x=180
Subtract 122 from both sides:
(122+2x)-122=180-122
Simplify:
2x=58
Divide both sides by 2:
2x/2=58/2
Simplify:
x=29
