Question

The value of 0 for which cos (10° + 0) = sin 30°, is
no​

Answer 1

Answer:

Hey there,

Let theta = X,

then,

cos (10° + X) = sin 30°

cos (10° + X) = 1/2

cos 60° = 1/2

10° + X = 60°

X = 50°

Answer 2

value of 0 is 50°

Step-by-step explanation:

given data

cos (10° + 0) = sin 30°

to find out

value of 0

solution

we know that

sin 30° = 0.5

and as we know

sin 30° = sin (90°- 60°)  

sin 30° = cos 60° ...............1

and

we have given

cos (10° + 0) = sin 30° .................2

put here equation 1 value

cos (10° + 0) = cos 60°

10° + 0 = 60°

0 = 60° - 10°

0 = 50°

so value of 0 is 50°
