Which types of triangles have rotational symmetry?

2 answers:

6 0

An isosceles triangle could have rotational symmetry if it were also an equilateral triangle. An isosceles triangle is a triangle with at least two equal sides. An equilateral triangle is a triangle with exactly three equal sides. By definition, all equilateral triangles are also isosceles triangles.

Answer:

8 Miles

Step-by-step explanation:

Start by creating an equation based off what you know. To start we know it costs $3 just to get a ride + $2 for ever mile we travel (represent this using x)+ the $1 tip we left=$20.

3+2x+1=20

Now you add the like terms together(3+1)

2x+4=20 Subtract the 4 from both sides.

-4 -4

2x=16 Now you just divide each side by 2

3. Write the equation of a line in slope-intercept form that passes through (9, 4) and is

konstantin123 [22]

⭐️- Remember that slope formula is y=mx+b

1. Know that the m is (-3)
2. 4=(-3)(9)+b
3. 4=(-27)+b
4. b=31
5. y=(-3x)+31
6. y=3x-31*

*whenever it is finding a perpendicular, you switch the signs; when it is finding a parallel, you leave it alone
