Answer 1

Answer:

Given: sin^2(120°)+co^2(300°)+tan^2(135°)

Step-by-step explanation:

So,

sin²(120°)+cos²(300°)+tan²(135°)

= sin²(180°-60°)+cos²(360°-60°)+tan²(180°-45°)

= sin²60°+cos²60°+tan²45°

= (√3/2)^2+(1/2)^2+(1)^2

= (3/4)+(1/4)+1

= [(3+1)/4]+1

= (4/4)+1

= 1+1

= 2 .....................(Ans.)
