Question

(2sin theta-1)(2sin theta +1) =0 find the value of theta​

Answer 1

here is ur answer

theta=30°

hope it helps....

Answer 2

Answer:

@=45

Step-by-step explanation:

(2SINE@-1) (2SIN @+1)=0

2SINE^2@-1=0                                                    (A+B) (A-B) = A^2 -B^2

SINE^2@=1/2

SINE@=1/ROOT2

SSIN@=SIN45

@=45
