You are standing beside the colorado river, 400 feet from the base of hoover dam. using an electrical distance measuring device, you find a distance to the top of the dam to be 965 feet. find the height of the dam

878.1941ft

Step-by-step explanation:

When you are standing in that position, you are making a 90º triangle with the hipotenuse of the trangle being 965 feet, and the base of the triangle would be 400 feet.

The laws of triangles dictate that the sum of both squared sides equals the hiponetnuse squared. The formula would be like this

If you clear the height you´d get:

You clear the height and it will end up like this:

Height=

Height= 878.19 feet.

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'.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
