Question

find the value of sin² 54+ cos²-54°​

Answer 1

Step-by-step explanation: The formula sin ^ 2 x + cos ^ 2 x = 1

that's the formula huh ..

so if the x is any (1,2, etc ..) and the value is the same, the result is still 1

so it is with sin ^ 2 54+ cos ^ 2 54 = 1

because x equals 54 and according to the formula above

so, the answer is 1
