The shape below is an equilateral triangle. a) Does the shape have rotational symmetry? If so, identify the angle of rotation. b) Does the shape tessellate?The image shows an equilateral triangle." i really need help to find this out

Below.

Step-by-step explanation:

a) An equilibrium  does have rotational symmetry.

The angle of rotation is 120 degrees .

It has Rotational  symmetry of order 3.

b) It does tessellate because the angle in the triangle divides exactly into 360 : 360 / 60 = 6.

4 times

Step-by-step explanation:

1 quart is equivalent to 32 fluid ounces.

If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:

Tanvi can make her volcano erupt 4 times  with 1 quart of vinegar.
