Step-by-step expla

Answer 2

Answer:

theta = 45

Step-by-step explanation:

1- sin ^2 a /cos ^ 2 a =tan theta

1 - ( 1 - cos ^ 2 a ) / cos ^ 2 a = tan theta

1 - 1 + cos ^ 2 a / cos ^2 a = tan theta

cos ^2 a / cos ^2 a =tan theta

1 = tan theta

the value of 1 comes on 45 degree in tan

theta = 45
