Объяснение:

При любом "а" сумма sin²a + cos²a равна 1

Поэтому sin²50°+cos²50° = 1

Answer 2

To find the value of sin²50° + cos²50°, we can use the trigonometric identity that states that the sum of the squares of the sine and cosine of an angle is always equal to 1. This identity is known as the Pythagorean identity.

The Pythagorean identity is given by:

sin²θ + cos²θ = 1

In this case, we are given the angle 50°. Plugging this value into the identity, we get:

sin²50° + cos²50° = 1

So, the value of sin²50° + cos²50° is equal to 1.

I hope this helps! Let me know if you have any further questions.
