Question

please tell me the correct answer​

Answer 1

❁Required Answer:

1 and 2 form a linear pair

so,

$45 \: + x = 180 \\ x = 45 - 180 \\ x =1 35 \: \\ therefore \: 2 = 135$

• 1 and 7 are alternative exterior angle therefore 7= 45°
• 2 and 8 are alternative exterior angle therefore 8= 135°
• 1 and 5 are corresponding angle therefore 5= 45°
• 2 And 6 are also corresponding angle therefore 6= 135°
• 6 and 4 are alternative interior angle therefore 4 = 135°
• 3 and 5 are alternative exterior angle therefore 3 = 45°

1 =45°,2=135°,3= 45°,4=135°,5=45°,6=135°,7=45°,8= 135°

❁Definition:

• Two lines meet at the common point is called an angle.
