Question

12 costhetha- 16 sin thetha = 0 find 2sin thetha + cos thetha
​

Answer 1

Answer:

Answer is 10sinθ/3

Step-by-step explanation:

12cosθ - 16sinθ = 0 (given)

To find =

2sinθ + cosθ -------- i)

Solution:

cosθ = 16sinθ/12

cosθ = 4sinθ/3

substitute in i)

= 2sinθ + (4sinθ)/3

= (6sinθ + 4sinθ) / 3        (by LCM)

= 10sinθ/3

Answer is 10sinθ/3
