When solving label 7. 8. 9. so ik which one ur doing. do all three though

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

8. Data:

arc AD = 136

arc CB = 96

< 1 = ?

Step 02:

< 2 = (arc AD + arc CB) / 2

< 2 = (136 + 96) / 2 = 116

< 1 = 180 - (< 2)

< 1 = 180 - 116 = 64

The answer is:

< 1 = 64°
