Question

if the cost of 3 x minus 10 is equal to sin x then the value of x is​

Answer 1

Answer:

1/2 1 divided by 2

Step-by-step explanation:

3×-10=sinx

-30 =sinx

then sin30 1÷2

Answer 2

Answer:

cos(3x - 10 ) = sin x

cos(3x - 10 ) = cos ( 90 - x)

=> 3x - 10 = 90 - x

=> 3x + x = 90 + 10

=> 4x = 100

=> x = 100\ 4 = 25

so, x = 25

Step-by-step explanation:

use the formula cos ( 90 - ∅) = sin ∅
