Answer:
Step-by-step explanation:
The three angles have a common point. The sum of the angles formed at a point is 360 degrees. This means that
(x - 25) + (2x - 65) ,+ 3x = 360 degrees
x - 25 + 2x - 65 + 3x = 360
x + 2x + 3x - 25 - 65 = 360
6x - 90 = 360
6x = 360 + 90 = 450
x = 450/6 = 75 degrees
Therefore
1) angle (x - 25) = 75 - 25 = 50 degrees
2) angle (2x - 65) =23 × 75 - 65 = 150 - 65 = 85 degrees
3) 3x = 3 × 75 = 225 degrees
