Answer:
C. 120º
Step-by-step explanation:
so we know that the inside of a triangle is 180º and since all the measures are the same we can do 180/3 to find how much each angle is.
180/3 = 60º
now we also know that a straight line is equal to 180º and since we already have one angle, all we have to do is subtract 60 from 180.
180 - 60 = 120º
Answer:
90°
Step-by-step explanation:
X=180°-(45°+45°){being square property}
X=180°-90°
X=90°
Answer:
Donna traveled for 8 hours at 90 mph
Maple traveled for 4 hours at 50 mph
Step-by-step explanation:
The velocity at which each person traveled is given by the distance traveled divided by the time spent (t). From the information given, the following expressions can be written
Therefore, Donna traveled for 8 hours at 90 mph and Maple traveled for 4 hours at 50 mph.
