Answer 1

Answer:

hope u understood this

Answer 2

Step-by-step explanation:

ii) 2x + 6x + x = 180 (Angle Sum property)

9x = 180°

x = 20 °

therefore,

<p = 2x = 2× 20 = 40°

<q = 6x = 6 × 20 = 120°

<r =x = 20

iii) x + x + 40 = 180 (Angle Sum property)

2x +40 = 180

2x = 180 - 40

2x = 140

x = 140 ÷ 2

x = 70

therefore,

<x = 70

<y = 70

<z = 40

iv) 3x + 2x + 90 = 180 (Angle Sum property)

5x + 90 = 180

5x = 180 - 90

5x = 90

x = 90 ÷ 5

x = 18

therefore,

<l = 3x = 3 × 18 = 54

<m = 90

<n = 2x = 2 × 18 = 36
