Question

2. If cos (40+ x)° = sin 30°, find the value of x.
3. If sin (A + 20)° = Y., then find the value of A.
4. If sin A=cos A, A is the acute angle, then find the
value of A.
5. Find the value of sin? 30° + cos2 60° + tan 45º
6. Find the value of 2 tan45° + cos2 30° –
sin? 60° please help me I have exam tomorrow please ​
