Question

plzzz solve it answer is 25

Answer 1

the answer is c because it can have the same y

Answer 2

Answer:

value of a² + b² is 25

Step-by-step explanation:

Given

a x + b y = 3

b x - a y = 4

and x² + y² = 1

To find = a² + b²

It is based on the trigonometric identity in which

a sinФ + b cos Ф= m

b sinФ- a cosФ = n

Then a² + b² = m² + n²

Similarly in the given equation  x = sinФ , y = cosФ

So, the value of a² + b² = 3² + 4² = 25

Hence the value of a² + b² is 25
