Answer 1

Answer:

∠y = 65°

∠x = 35°

∠z = 120°

Step-by-step explanation

If we extend the line DC we get ∠e as shown below

∠e = 80° Alternate interior angles

∠e+∠d = 180°  They lie on the same straight line

Putting the values

80° +∠y + 35° = 180°

115° + ∠y = 180°

∠y = 180° - 115°

∠y = 65°

∠CBD = ∠y - 30° = 35°

∠x = 35° Alternate interior angles

∠z = 360° - (∠a+∠b+∠d)

∠z = 360° - (80°+65°+95°)

∠z=360° - 240°

∠z=120°

Answer 2

Answer:

A pencil when dipped in water in a glass tumbler appears to be bent at the interface of air and water. will the pencil appear to be bent to the same extent, if instead of water we use liquids like, kerosene or turpentine. support your answer with reason.
