Thehe minimum weight of the 20 student is 20 kg. If their range is 20 kg, find the maximum weight and the coefficient of range

1/3

Step-by-step explanation:

Range=x maximum (xm) –x minimum (x0)

xm=20+20=40

Coefficient of Range= xm–x0/xm+x0

=40-20/40+20

=20/60

=2/6

=1/3

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

h= 12 inches
