an angle of elevation of the top of a church is 47 degree . if the tower is 31 meters above the ground how far from the tower is the point of the elevationwas taken . correct to 2 decimal place

Step-by-step explanation:

Angle of elevation = α = 47 degrees

Height of the church = opposite = 31  m

Distance from point to the church = adjacent = x

So,

Tan α =

Tan (47) = 31/x

=> 1.07 = 31/x

=> x = 31/1.07

=> x = 28.91 m (Upto 2 dps)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
