Question

please solve this Question number 4 and 5

Answer 1

question no. 4
angle 1 + angle 4 = 180° (linear pair)
71° +angle4 = 180°
angle 4 = 180-71°
angle 4 =109°
angle 3 = angle 1 ( v.o.a.)
angle 3 =71°
remain angles you can find by alternate angle

Answer 2

Question no.5
3x+4°+ x°=180°. (Sum of co-exterior angles is 180°)
So,
4x+4=180
4x=176
x=44°
Angle1=x=44°. ( v.o.a)
Angle2=3x+4=3(44)+4=132+4=136°
