Answer:
the answer is 1.
Step-by-step explanation:
cos30 can be qritten as sin 60 and sin 30 can be written as cos 60.
as we know cos(90-theta)= sin theta. and vice versa
then sin^2 60 + cosa^2 60 becomes 1 as sin ^2 theta + cos^2 theta = 1 or you can place the values of sin 60 and cos 60 also you will get the answer.
Hope you understood!
