128 = 2^7 = 2*(2^3)^2
sqrt(128) = sqrt(2*(2^3)^2) = 2^3*sqrt(2)
The rate of the slower cyclist is 16 mph while the rate of the faster cyclist is 21 mph.
<h3>How to calculate the rate of speed?</h3>
let us assume the following;
x = rate of slower cyclist
x + 5 = rate of faster cyclist
We know that formula for distance is;
distance = travel time*rate
Thus;
2x + 2(x + 5) = 74
Since the two cyclists are a distance of 74 miles apart after a time 2 hours. Thus;
2x + 2x + 10 = 74
4x + 10 = 74
4x = 74 - 10
4x = 64
x = 64/4
x = 16
Rate of faster cyclist = 16 + 5 = 21 mph

Answer:
x = 48
Step-by-step explanation:
Supplementary angles sum to 180°
add the 2 angles and equate to 180
x + 3x - 12 = 180 ( add 12 to both sides )
4x = 192 ( divide both sides by 4 )
x = 48
