Answer 1

i) sin x°= 8/17

ii) cos y° = 6/ DC

DC = sqrt ( 8^2 + 6^2) = sqrt(100) = 10

cos y° = 6/10 = 3/5 , sin y° = 8/10 = 4/5

iii) 3tan x° -2 sin y° + 4 cos y°

= 3 ( 8/ (AD +6))- 2×4/5 + 4 × 3/5

= 24/ (AD+6) - 8/5 + 12/5

= 24/(AD+6) + 4/5

Now, AD = AB - DB = AB - 6

AB = sqrt ( AC^2 - BC^2)

= sqrt ( 289-64) = sqrt(225) =15

So, AD = 15-6 = 9

Therefore,

Expression = (24 / (9+6)) + 4/5

= 24/15 +4/5 = 8/5 + 4/5 = 12/5
