Answer 2

The equation you've written, sin(25°)cos(35°) + cos(25°)sin(35°) = 3/2, is known as the angle addition formula for trigonometric functions. However, this equation is not correct. The actual value of the expression sin(25°)cos(35°) + cos(25°)sin(35°) is approximately equal to 0.4205.

To verify this, let's calculate the expression step by step:

sin(25°)cos(35°) + cos(25°)sin(35°) = (0.4226)(0.8192) + (0.9063)(0.5736) = 0.3465 + 0.5202 = 0.8667

Therefore, the value of sin(25°)cos(35°) + cos(25°)sin(35°) is approximately 0.8667, which is not equal to 3/2 (1.5).

Please double-check your calculations or provide additional context if there's a different equation you'd like me to address.
