Step-by-step explanation:
1) 2x + 246 = 360° (Vertically opposite and angle at a point)
2x = 360 - 246
2x = 114°
x = 114 / 2
x = 57°
3) Since <ABD is a right angle (i.e its sum is 90°)
<CBD = 90° - 75° = 15°
5) <1 = <2 (Vertically opposite angles are equal)
12x + 3 = 10x + 15
12x - 10x = 15 - 3
2x = 12
x = 6
Therefore,
<2 = 10(6) + 15
<2 = 75°
