For Problem #2, the second one should be 6x+4x+12, and the third one should be 10x+12
Answer:
RSQ is 105° and RPQ is 30°
Step-by-step explanation:
since S is the incenter of PRQ and RQP the angles are divided by 2
then use angle sum property that is 45+30+s=180
75+s=180
s=180-75
s=105
400 miles -----------4 hours
X miles ------------2 hours
4x=400.2
4x=800
X=200
Or
400miles --------------- 4hours
X miles --------------- 6 hours
4x=400.6
4x=2.400
X= 600
