Answer:
The answer to your question is: x = 32
Step-by-step explanation:
Data
x = ?
It is an equilateral triangle so, the three angles measure the same
2x - 4 = 5y
2x - 5y = 4
The sum of the internal angles in a triangle equals 180°
3(5y) = 180
5y = 180/3
5y = 60
y = 12
2x - 4 = 5y
2x - 4 = 5(12)
2x = 60 + 4
2x = 64
x = 64/2
x = 32
8368 is 10 more than 8358
Total distance = 20 km = 20 000 m
walk = 800 m
cycle = 20 000 - 800 = 19 200m
percentage of the journey =
x 100% = 96%
