Answer:
X° + 2x° + 45° = 180°
X = 45°, 2x = 90°
Step-by-step explanation:
Since the angles in a triangle sums up to 180
And the angles in this particular triangle is measured as 2x° + x° + 45° = 180
With this equation, we can find the value of x and 2x
2x + x + 45 = 180
3x + 45 = 180
3x = 180 - 45
3x = 135
Now divide both sides by 3
3x/3 = 135/3
X = 45
Therefore, the angles of that triangle are x° = 45, 2x°= 45 × 2 = 90° and the third angle which was given to us as 45°
