Question

sin 30 degree -sin 90 degree +2 cos 0 degree ......................=tan 30 degree tan 60 degrees​

Answer 1

Step-by-step explanation:

sin30=1/2

sin90=1

cos0=1

tan30=1/√3

tan60=√3

put the value ;

1/2-1+2= 1\√3×√3

3/2=1

please rate it

Answer 2

1/2-1+2 X .........=1/✓3×(✓3)

-1/2+2x=1

2x=1+1/2

2x=3/2

x=3/4

OR

1/2-1+2 -sin^2(45°)=1

1/2+1-(1/✓2)^2=1

1/2+1-1/2=1

1=1

........= -sin^2(45°)
