Solution :
Given that :
The radius of circle A = 6 cm
The radius of circle C = 4 cm
In circle A

The length of arc EF = 

= 14.653 cm
In circle C

The length of arc GH = 

= 9.769 cm
Therefore,
The length of EF is 14.653 cm
The length of GH is 9.769 cm
The length of EF is 1.5 times the length of GH
i.e. 14.653 = 1.5 x 9.769
14.653 = 14.653
Hence proved.

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°
