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:
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°
