Answer: Mary covers less distance for 320 m
Step-by-step explanation:
Psqere=4a
Prect=2(a+b)
anna=4*4a (a=90m)
Anna=16*90=1440m
Mary=4*2(a+b)=8(a+b)=8*(80+60)=8*140=1120 m
anna-Mary=1440-1120=320m
Answer:
89 degrees
Step-by-step explanation:
The angle 1 is the same as angle 3.
Angle 2 is the same as angle 4.
The sum of these four angles is 360 degrees.
We have that:
Angle 2 = Angle 4 = 7x - 14
Angle 3 = Angle 1 = 5x + 14
Finding x:
Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360
2*(5x + 14) + 2*(7x - 14) = 360
10x + 28 + 14x - 28 = 360
24x = 360
x = 15
Angle 1:
5x + 14 = 5*15 + 14 = 89 degrees
