Answer:

1 + 1 = 11! :D No, just kidding 1 + 1 = 2

Step-by-step explanation:

1 + 1 = 2. You're taking 2 numbers (1) worth 1 value and adding them together to make the number 2.

I dont know how to explain but I hope this cures your curiosity-

Answer: 1 + 1 = 2

Step-by-step explanation:because that's how we've defined it, in the same way that the word "cat" refers to small, furry, feline creatures because that's how we've defined it.

In 1910, the population of Seattle, Washington, was 237,194. In 2010, the population had grown to 608,660. By about how much did

Wewaii [24]

You subtrscy the bigger number (2010's population) by the smaller one (1910's population). 237194-608660= 371,466.

When you round to the 100's you check the 10's place. If 5 or higher add a 1 to the hundreds place, and make the 1's and 10's place 0. If lower don't add anything and make the 1's and 10's place into 0s.

When you round it, you will get 371,400

What is the hight of a Building 1 Angle 71o Distance 20 meters

vlabodo [156]

The height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.

<h3>What is trigonometry?</h3>

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

Angle = 71 degree

Distance between A and B = 20 meters

Let's suppose the height of the building is x meters.

From the right angle triangle applying the tan ratio:

tan71 = x/20

x = 58.08 meter

Thus, the height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.
