Answer 1

Explanation:

this is how I do it in Vietnam, if you don't understand, ask me

Answer 2

• x = 70°

-----------------------------

According to the picture we have:

• ∠BAK ≅ ∠CBD as corresponding angles,
• ∠BDC ≅ ∠PDK as vertical angles.

Find the measure of angle PDK, using sum of angles of ΔPDK:

• m∠PDK + 60° + 70° = 180° -
• m∠PDK = 180° - 130°
• m∠PDK = 50°

Find x, using sum of angles of ΔBDC:

• x + 60° + 50° = 180°
• x = 180° - 110°
• x = 70°
