Answer:- Equilateral triangle has an order 3 rotational symmetry.
Explanation:-
In geometry, a figure has rotational symmetry if it moves onto itself under rotation about an angle at center of rotation.
The order of rotational symmetry is the number of times the shape moves onto itself throughout a rotation of 360°.
An equilateral triangle has all its sides equal with equal interior angle of 60°.
It moves onto itself three times throughout a rotation of 360°.
⇒Equilateral triangle has an order 3 rotational symmetry.
Answer:
The coefficients are b and a
Yes, a trinomial is also a polynomial.
Answer:
Step-by-step explanation:
8x^2 - 4x
4x(2x - 1)
GCF is 4x
Since the triangles are similar, the ratio of the sides of larger triangle to the smaller triangle is a constant.
That constant =

Since the sides are in that constant proportion, the area of the triangles will also be in proportion.
(Area of larger triangle) over (Area of smaller triangle) =



= 123.6 ≈ 124
Hence, to the nearest whole number the area of smaller triangle is 124 <span>ft</span>²<span>.</span>
