Can you form a unique triangle,more than one,or no triangle with the angles that measure 50 degrees,90 degrees,and 110 degrees? Explain. Support you explanation with drawings.

Answers

Answer: No triangle is possible

Explanation

Add up the angles:

50+90+110 = 140+110 = 250

The angles do not add to 180, so a triangle is not possible.

The rule is that the interior angles of any triangle always add to 180 degrees.

As for the drawing part, you can use a protractor to measure out each angle to see why a triangle can't be formed. GeoGebra is another useful tool.

Answer:

Step-by-step explanation:

We cannot form a triangle because sum of all interior angles of a triangle is 180 degrees.

Here,

50 + 90 + 110 = 180

250 ≠ 180

Hence, we cannot form a new triangle.

Match the equivalent expressions.

Answers

Answer:

Step-by-step explanation:

1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12

2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12

3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12

4. I do not know unfortunately

Answer:

See attached image

Step-by-step explanation:

To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest

Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2

To simplify,

group like terms:

=(4y + 3y - 6y) + 3x +(-10 -2)

= y + 3x - 12

Rewriting with x before y gives
3x + y - 12

and there is a matching 3x + y - 12

4y + 3y + 3x - 6y -10 - 2 ⇔ 3x + y - 12

The solution is in the attached image

Well anyways i hope this clears your concepts :D

Answer:

Step-by-step explanation:

EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).

Angle G remains the same at 55 degrees.

PART A

Scale factor for the triangle = 1/4

Value of y = 28cm

3) z = 5, scale factor = 5

When we perform rigid transformations on parallel lines, what do we know about their image? Does the distance between the lines change?

Answers

Answer:

The distance between each line does not change.

Explanation:

Because you are just transforming it. It's not like you are changing the shape at all, you are just moving it to a different area on the grid. You can transform it over the x-axis, or you could transform it over the y-axis. It doesn't matter. Hope that answered your question.

Answer: the length between every line wouldn't´ change

Step-by-step explanation:

A rigid transformation changes the location of a shape without changing the size of the shape. There are three basic rigid transformations: reflections, rotations, and translations.
