Answer:
Ok so you want to find the relationship between triangle ADEe and ABC, so you can compare 2 corresponding sides. You have the lengths of AD and AB, so to find the relationship you can do AD/AB. AD = 3 and AB = 5, so that means the relationship is 3/5. Then, you can compare DE and BC. If BC is x, you would have:
3/5 = 6/x
so you know that 3/5 = 6/10, so x= 10
An inscribed angle has value half the arc measure, so
x = 51 degrees
Answer:
1. x≥-2
2. x<-2
Step-by-step explanation:
Answer:
ABQ = 139
BCR is the same as QBC since they are alternate interior angles
BCR = 41
Step-by-step explanation:
CBQ and SCB are same side interior angles so they add to 180
2a-9 + 5a +14 = 180
Combine like terms
7a +5 = 180
Subtract 5 from each side
7a = 175
Divide by 7
7a/7 = 175/7
a = 25
ABQ is the same as SCB since they are corresponding angles so
ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139
BCR is the same as QBC since they are alternate interior angles
BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41
