Question

sin^2(x/2)+ cos^2(X+30/3)=tan45 then find the value of x.​

Answer 1

Answer:

X=60

Step-by-step explanation:

Answer 2

Answer:

solved

Step-by-step explanation:

Sin^2(x/2)+ cos^2(X+30/3)=tan45

Sin²(x/2)+ cos²(X+10)= 1

2Sin²(x/2)+ 2cos²(X+10)= 2

1 - cos x + 1 + cos (2x+20) = 2

cos (2x+20) = cos x

2x + 20 = ± x , 360n ± x

for 0≤x≤360

 2x + 20 = x , 360-x

2x = x - 20 , 340 - x

x = - 20° ,  340°/3
