Question

Value of sin²60°+cos²45

Answer 1

Step-by-step explanation:

sin²60°+cos²45

=(root 3/2)^2+(1/root2)^2

=3/4+1/2

=(3+2)/4

=5/4

Answer 2

Answer:

5/4

Step-by-step explanation:

sin²60°+cos²45=?

sin60°=root3/2

so,sin²60°=root3/2 Xroot3/2= 3/4

cos45=1/root2

cos²45=1/root2X1/root2=1/2

Now,

sin²60°+cos²45= 3/4+1/2

                         =3/4+2/4

                         =5/4
