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:
105/9
Step-by-step explanation:
180 - 132 = 48 degrees
180 - 48 - 45
= 180 - 93
= 87 degrees
<2 = 180 - 87
= 93 degrees
=> 9x - 12 = 93
=> 9x = 105
=> x = 105/9
For this case we have to take into account the following conversions:

Let's first transform the expression to miles per seconds squared:

Then, we transform the result to miles per minute squared.
We have then:
Answer:
the rate in miles/min^2 is:
