Answer:
black line <3
Step-by-step explanation:
the slope is -2 :)
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°
You solve for x and get x<-2 or x>= -1/2 and then graph
Im not sure about the second one, but for the first one, Alex’s height is 167.64 cm. :)
