Question

Given that sin 2x = 1 and cos y =√3/2, then find the value of x –y.

Answer 1

ᴀɴswєя :-

sin2x = 1

sin90° = 1

sin2x = sin90°

2x = 90°

x = 45°

cosy = √3/2

cos 30° = √3/2

cosy = cos30°

y = 30°

Answer 2

Answer:

15°

Step-by-step explanation:

Given:

sin 2x = 1

cos y = √3/2

To find:

x-y

Solution:

sin 2x = 1

sin 2x = sin 90°

2x = 90°

x=45°

cos y = √3/2

cos y = 30°

y=30°

∴x-y = 45°-30°

       = 15°
