QuestionEvaluate $\sin^{2}(28^{\circ}) + \cos^{2}(28^{\circ})$ and simplify your answer to find the value.

Studdy Solution
So, without using a calculator, we can say that the value of the expression $\sin ^{2}\left(28^{\circ}\right)+\cos ^{2}\left(28^{\circ}\right)$ is1.
The expression $\sin ^{2}\left(28^{\circ}\right)+\cos ^{2}\left(28^{\circ}\right)$ simplifies to1.
