The hypotenuse of a right triangle is 50 meters long and one side is 30 meters long What is the length of the remaining side

40 metres.

Which of these rates is slowest 1760 yardsminute 60 mihr or 88 ftsec

When you convert it, you will find out that they're all the same.

The tangent of an angle equals the ratio of the

Sine of the angle to its cosine.

If I have a right triangle The side opposite angle A is 6 meters and the side adjacent angle A is 8 meters How long is the hypotenuse

The hypotenuse is: 10

Dallas is 200 miles from Oklahoma City You average 40 miles per hour and your friend averages 50 miles per hour How long will your friend have to wait for you to reach Dallas

Your friend will have to wait one hour: Covering 200 miles at 50 miles/hour requires 4 hours, while covering the same distance at 40 miles/hour requires 5 hours.

The sine of a 37 degree angle

0.602

In the metric system the prefix for 110 is

The metric system is designed to deal in powers of ten, so it has a prefix for 100, which is hecto, but not for 110.

If the side opposite angle A of a right triangle is 30 meters and the hypotenuse is 90 meters what is the value of the sin of angle A Round the answer to the nearest hundredth

0.33

You drive a car 2 hours at 40 miles per hour 2 hours at 60 miles per hour how many miles will you travel

If you drive a car at 40 miles per hour for two hours,then the distance covered will be 80 miles.If you drive the car for another 2 hours at 60 miles per hour ,then you will cover another 120 miles.The total distance you will cover is thus 80 miles + 120 miles = 200 miles.

The tan of a 45 degree angle

1.00

What type of measurement is this 12 feet up scalar or vector

A scalar has distance but no direction.

A vector has distance and direction.

"12 feet up" has distance (12 feet) and direction (up), so is a vector.
