Answer 1

Answer:

iii)x=20

iv)x=60

y=40

z=60

140+y=180

y=40

180-130=z

z=50

vi)x by angle A= 30

x by angle C=30

Step-by-step explanation:

iii) 2x+3x=5x

180-80=100

5x=100

x=20

iv) x+y+z=180

vi) 180-130=60

x+x=2x

2x=60

x=30

hope it helped and that its right

Answer 2

Answer:

i) angle a = 50⁰

<b = x

<c = 180- 125 (linear pair)

55°

find angle b

x + 50 + 55 = 180 (angle sum property)

x + 105 = 180

x = 180 - 105

x = 75°

ii) <A = 2x

<B = 180 - 120 (linear pair)

= 160°

<C= x

to find the remaining angles

x + 2x + 75 = 180° (angle sum property)

3x + 75 = 180

3x = 180- 75

3x = 105

x = 105 ÷ 3

= 35°

< C = 35 °

< A = 2 × 35 = 70°

iii) <a = 180 - 80 = 100 ( L. P)

< b = 2x

< c = 3x

to find remaining angles

100 + 2x + 3x = 180 (angle sum property)

100 + 5x = 180

5x = 180 - 100

5x = 80

x = 80÷ 5

x = 16

<b= 2× 16 = 36

<c= 3 × 16 = 48

iv) <a = x

< b = 180 - 140 (L.P.)

=40°

< c = 180 - 130 (L. P.)

= 50°

to find angle A

= x + 40 + 50 = 180 (angle sum property)

= x + 90 = 180

= x = 180-90

= x = 90 °

<c = 90°

v) < a = x

< b = 55°

<c = 180 - 125 = 55° (L. P.)

to find angle A

x+ 55 + 55 = 180 (angle sum property)

x + 110 = 180

x = 180 - 110

x = 70

<a = 70 °

vi) <a = x

< b = 180- 130= 50 (L. P)

<c = x

to find remaining angles

x + x + 50 = 180 (angle sum property)

2x = 180- 50

2x = 130

x = 130 ÷ 2

x = 65°

<a and <c = 65°
