Answer 1

Answer:

1

Step-by-step explanation:

Sin square thetta +cos sqare thetta = 1

Answer 2

Answer:

sin square 60 + cos square 60=1 bcz we learn that identity sin sq. x+ cos sq. x=1 , where x is any angleor u can prove it by using abv identity we can write sin sq.x +cos sq x = 1 similarly sin sq. 60 + cos sq. 60 =1-cos sq.60+ cos sq. 60=1[bcz we knw sin sq. x +cis sq. x=1 which implies sin sq. x=1-cos sq. x]
