If r=20.5 and s=34.2 find s round to the nearest tenth

option d

Step-by-step explanation:

Remember the identity:

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "S":

Knowing that: you need to find the measure of the angle "S" , (which is the adjacent side) and (which is the opposite side), you can sustitute values into

Then, you get that the measure of "S" rounded to the nearest tenth is:

d

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
