Answer 1

Solution:

• We know, the sum of the angles on a line is 180°.
• Therefore,

(12x+20)°+(7x+8)° = 180°

or, 19x° + 28° = 180°

or, 19x° = 180°-28°

or, 19x° = 152°

or, x = 152° ÷ 19°

or, x = 8

• Therefore, (12x+20)° = (12×8+20)° = (96+20)° = 116°
• We also know that vertically opposite angles are equal.
• So, z° = 116° or, z = 116

Answer:

x = 8

z = 116
