Answer 1

Answer:

The Answer to this Question is 7

Answer 2

Answer:

4tanx = 3

tanx = 3/4 = Opposite/Adjacent

Therefore, in Triangle ABC,

3² + 4² = AC²

AC² = 9 + 16 = 25

AC = 5 units = Hypotenuse

Therefore,

cos x = 4/5, sinx = 3/5

cosx + sinx = 4/5 + 3/5 = 7/5 ---- (1)

cosx - sinx = 4/5 -3/5 = 1/5 ---- (2)

(1) ÷ (2)

(cosx + sinx)/(cosx-sinx) = 7/5 ÷ 1/5 = 7/5 * 5

= 7.
