Answer» Answer: We know both TRIANGLE are in ration 7:8 We can TAKE first angle as 7X other as 8x other angle is SUM of these (15x) So 7x + 8x + 15x Hence 15x = 180 ( Angle Sum) x = 180/15 =x = 6 first angle is 7 x = 7 x 6 =42 second angle is 8x = 8 x 6 =8x = 48 third angle is 15x = 15 x 6 =15x = 90 |
