Step-by-step explanation:
Twelve and six hundred seven thousandths
Answer:
10,
Step-by-step explanation:
The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.
The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200
y = √200 = √100√2=10√2
So.. traveling without the wind, let's say the pedalist has a speed of "r"
with the wind, the wind's rate is added to it, so, he's not going "r" fast, he's really going r+3 fast
against the wind, he's going r - 3 fast
notice, he covers 30 miles with it, and 18 miles against BUT the time for both ways is the same, say time "t"
now, recall your d = rt, distance = rate * time
thus
solve for "r"
