Answer:
width: 7.5
length: 22.5
Step-by-step explanation:
width: x
length: 3x
Perimeter = 2L + 2W
60 = 2(3x) + 2x
60 = 6x + 2x
60 = 8x
x = 7.5
width: x = 7.5
length: 3x = 3(7.5) = 22.5
Answer:
221°
Step-by-step explanation:
Using sine rule
a/sinA = b/sinB = c/sinC
A= 36°
B= 37°
C = 107°
It takes 90 seconds to go from point A to point B. To find a, we will use
a/sinA = c/sinC
a/sin36°= 360/sin 107°
a(sin 107°) = 360sin36°
a = 360sin 36° / sin 107°
a = 360(0.5878) / 0.9563
a = 211.608/0.9563
a = 221.27°
a = 221°
