number one is x= 415=3 43 =3.75
number two is a= 45(b+2)
Opposite angles have the same measure. So, we can set the following equation:
From here, we can forget about the geometry and continue algebraically: subtract 2x from both sides:
Add 52 to both sides:
Answer:
15y=-1/3x+5
Step-by-step explanation:
-5x15y=-5x+75
Distance = 200 km
Speed = 35.27 km/h
Time = Distance / speed
= 200 km / 35.27 km/h
= 5.67 hours
so he skated for 5.67 hours
