Question

Please solve the above question

Answer 1

Answer:

73. C) 8

Here the rule in all the triangle is add the last two angles subtract by first angle and then divide the result by two in every case. see the first triangle

6 +7=13(sum of last two angles)

13-3=10( difference of sum and first angle)

10/2=5(result divided by 2)

see the second triangle

12+8=20(sum of last two angles)

20-14=6( difference of sum and first angle)

6/2=3(result divided by 2)

similarly the third triangle

13+5=18(sum of last two angles)

18-2=16( difference of sum and first angle)

16/2=8(result divided by 2)
