Answer
1= 60 degrees
2= 50 degrees
3= 70 degrees
4= 110 degrees
5= 120 degrees
Work Step by Step
1 and 60 degrees are alternate interior angles. Therefore, 1= 60 degrees.
1, 2 and 70 degrees lie on the same line which means that their sum is 180 degrees. Since we know the value of 1, 2 equals 50 degrees.
3 and 70 degrees are alternative interior angles. Therefore, 3 = 70 degrees.
3 and 4 lie on the same line which means that their sum is 180 degrees. Since we know the value of 3, 4 is automatically calculated as 110 degrees.
5 and 60 degrees lie on the same line which means that their sum is 180 degrees. The value of 5 is therefore calculated as 120 degrees.
