Answer :
Answer:
2x=28
Step-by-step explanation:
To find the value of x, we can use the fact that the sum of the angles in a triangle is 180°.
In this case, we have:
ZA + ZB + ZC = 180°
Substituting the given values:
(5x - 60°) + (2x + 40°) + (3x - 80°) = 180°
Simplifying the equation:
5x - 60° + 2x + 40° + 3x - 80° = 180°
10x - 100° = 180°
Adding 100° to both sides:
10x = 280°
Dividing both sides by 10:
x = 28°
Therefore, the value of x is 28°.
