Answer

25

Explanation

sin (x + 22)° = cos (2x - 7)°

In trigonometry for any equation where sinθ = cosΦ, θ and Φ are complementary. That is they add up to 90°

sinθ = cosΦ   ⇒ θ + Φ = 90

∴ sin (x + 22)° = cos (2x - 7)°

    (x + 22) + (2x - 7) = 90

    x + 22 + 2x - 7 =90

    3x + 15 = 90

    3x = 90 - 15

      3x = 75

         x = 25°
