Question

find the value of:sin square 60° +cos square 45°​

Answer 1

Hey there!! here's your Answer:

sin^2 60+cos^2 45= 5/4

Step-by-step explanation:

we know that,

sin60=$\sqrt{3}$/2

cos45= 1/$\sqrt{2}$

=> sin^2 60+cos^2 45=   ($\sqrt{3}$/2)^2 +(1/$\sqrt{2}$)^2

                                   =  3/4+ 1/2

                                   =3+2/4

                                   = 5/4

Hope I was able to help!!
