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

Answer:

all the angles in a triangle will add to 180

65 + 57 + 2x = 180

subtract the 65 and 57 from both sides

2x = 58

x = 29

D) 29
