Triangle ABD is i<span>nscribed in circle and </span>has hypotenuse as circle's diameter so angle ABD must be 90°
Since it is parallelogram, ∠ABD = ∠BDC = 90° and it is given that ∠ADB = 30°
So we have ∠CDO = ∠CDB + ∠ADB = 30° + 90° = 120°
Final answers: ∠CDO = 120° and ∠ABD = 90°
Answer:
- Parallel
- Neither parallel nor perpendicular
- Perpendicular
Step-by-step explanation:
<u>Given line m:</u>
<u>Relationship of line m with following lines:</u>
1.<u> y = 4/5x + 3</u>
- Same slope, different y-intercept
- Parallel
2. <u>y = -4/5x + 3</u>
- Slope are negative, different y-intercept
- Neither parallel nor perpendicular
3. <u>y = - 5/4x + 3</u>
- Slopes are negative-reciprocal, different y-intercept
- Perpendicular
