Question

in triangle and right angled at c and = 29 units , bc = 21 units and angled and = theta the value of cos square theta + sin square theta is equal to

Answer 1

Let the angle B be theta
AC = 29 units (p)
BC = 21 units (b)

We know that,
${ \cos }^{2} \theta + { \sin }^{2} \theta = 1$

Therefore, the answer is 1.
