Question

If sin30 = cos (50 + x), find the value of x.. *​

Answer 1

Answer:

the value of x is 10

Step-by-step explanation:

sin 30= cos ( 50+x)

and

sin 30 = cos (90 - 30)

So,

cos ( 50 + x ) = cos (90-30)

then, 50+x = 90-30

x = 60-50

x = 10

Answer 2

Answer:

x = 10

Step-by-step explanation:

we know, sin θ = cos(90-θ)

here given,

sin30 = cos(50+x)

=> 50+x = 90-30     [ ∵ sin30 = cos(90-30) ]

=> 50+x = 60

=> x = 60-50

=> x = 10
