Question

if 2sin(A+B)=1 and 2cos(A-B)=2 find A and B​

Answer 1

Step-by-step explanation:

step by step explanation is attached.

we have to just use here trigonometric formula and solve the simultaneous equations.

Answer 2

Answer:

$sin(a + b) = \frac{1}{2} \\ a + b = 30$

$cos(a - b) = 1 \\ a - b = 0$

so, solving the above equation

$a = 15 \: and \: b = 15$
