I need this answer really quick PLEASE.
1 answer:
Answer:
- m∠1 = 12°
Step-by-step explanation:
The axis AB is passing through the center O as it hold the diameter.
OC⊥AC as tangent is perpendicular to radius.
<u>∠BOC is the central angle and is of same measure as intercepted arc BC:</u>
- m∠BOC = 102°
<u>∠BOC is exterior angle to ΔAOC, hence is equal to sum of non-adjacent interior angles:</u>
- m∠BOC = m∠OAC + m∠OCA
- 102° = m∠1 + 90°
- m∠1 = 102° - 90°
- m∠1 = 12°

- and you know the values of both of them you will simply substitute them with their values and answer the question in the form of an equation as shown in the photo
