Gwar [14]3 years ago
5 0

Answer:

Step-by-step explanation:

The sum of the interior angles of a polygon with n side is

180(n-2)

So, for a polygon with 5 sides the expression is

180\cdot 3 = 540

The measure of hypotenuse using the ruler is 25.5 cm and using the formula is 23.43 cm, they are not same, and formula can be used to in the real life problems as well.

<h3>What is a right-angle triangle?</h3>

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete:

The complete question is:

Present a picture of an object (TV, Ipad Screen, Book Cover) that contains a right angle (it could be something in nature or that is man-made). Use a ruler or measuring tape to measure the two sides that make the right angle and measure the distance from the end of one side to the end of the other side (hypotenuse). Draw a diagram of the object including the measurements. Use your leg measurements on your diagram to calculate a theoretical hypotenuse. (Show all steps).

  • Does the hypotenuse that measured with a ruler/measuring tape equal the hypotenuse you calculated?
  • Why do you think they are or are not exactly the same?
  • What did you learn from developing this presentation?

We are assuming the length of one side x:

x = 18 cm

Length of other side y:

y = 15 cm

And length of the hypotenuse z:

z = 23.5 cm

From the Pythagoras theorem:

z² = x² + y²

z² = 18² + 15²

z² = 549

z = √54 = 23.43 cm

The measure of hypotenuse is:

Using ruler: x = 25.5 cm

Using formula: x = 23.43 cm

They are not equal due to the reading in the ruler.

The formula can be used to in the real life problems as well.

Thus, the measure of hypotenuse using the ruler is 25.5 cm and using the formula is 23.43 cm, they are not same, and formula can be used to in the real life problems as well.

The point (2, -3), is the top of a triangle. Which point would it map to if the triangle was translated up 7 units and reflected
Elza [17]

Answer: (-2,4)

Step-by-step explanation:

When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
