Answer 1

Step-by-step explanation:

Sin2(90-theta)+cos2(90-theta)

cos2(theta)+Sin2(theta). (sin2{a}+ code{a}=1)

1

Answer 2

Answer:

The correct answer is 1

Step-by-step explanation:

Given: Sin2(90-theta)+cos2(90-theta)

To find: value of the given equation

Sin2(90-theta)+cos2(90-theta)

we know that, Sin(90-theta)= costheta

therefore, Cos2(theta)+cos2(90-theta)

we know that, Cos(90-theta)= Sintheta

then the equation become,

=Cos2(theta)+Sin2(theta)

=1 {we know that Cos2(theta)+Sin2(theta)=1}

therefore, the final answer is 1
