please give the correct answer​

Answer 1

Answer:

(i) x = 130°

   y = 130°

   z = 130°

(ii) x = 90°

    y = 120°

    z = 120°

Step-by-step explanation:

(i) x = 180° -50° = 130°

   y = x = 130°

   z = x = 130°

(ii) x = 90°

    y = 180° - (90° +30°) = 180° -120° = 60°

    z = y = 60°

Answer 2

Answer:

On a hot summer day, when we sprinkle water on the roof or open ground, it evaporates quickly because of the heat of the sun. ... When sweat evaporates after absorbing the energy from the surrounding, it gives us a cooling effect. Thus, sweating helps us in maintaining our body temperature.
