Question

Find the value of k if cos 35/sin55 + 2sin theta/cos[90-theta] =k/2

Answer 1

cos35/sin55 + 2 sintheta/cos(90-theta) = k/2

cos (90- 55)/sin 55 + 2 sin theta/ cos (90- theta) = k/2


sin 55/sin 55 + 2 sin theta / sin theta = k/2


[since cos ( 90- A)= sin A ]

1 + 2 = k/2

3 = k/2

k/2 = 3

k = 2×3

k= 6

Answer 2

Answer:

$hay \: guys$

the value of k is 6

Step-by-step explanation:

cos(90-55)/sin 55 +2sin /sin =k/2

$cos(90 - theta) = sin \: theta$

sin55/ sin55 +2=k/2

1 +2 =k/2

3=k/2

k=6
