Answer 1

Answer:

Step-by-step explanation:

1) (x + 10)° + x° + (x + 20)° = 180° { linear pair}

x + 10 + x + x + 20 = 180°

3x + 30 = 180

3x = 150°

x = 50°

(x + 10)° = (50 + 10)° = 60°

x = 50°

(x + 20)° = (50 + 20)° = 70°

2) Angle Y = 62° {Vertically Oppo. Angles}

angle y + angle x = 180° {linear pair}

62° + angle x = 180°

angle x = 118°

angel x = angle z { vertically Oppo. angles}

118° = angle z
