The triangle lines of symmetry are 60 degrees apart option (A) 60 degrees is correct.
<h3>What is a regular polygon?</h3>
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
As we know,
The act of using mathematics to address issues in the actual world is known as mathematical thinking.
As the pentagon has 5 sides and 5 lines of symmetry.
The pentagon's lines of symmetry are apart 72(360/5) degrees apart.
Similarly in the triangle, the sum of the interior angle is 180 degrees
The triangle lines of symmetry are 60(180/3) degrees apart.
Thus, the triangle lines of symmetry are 60 degrees apart option (A) 60 degrees is correct.

Answer:
1. (3x²y³z)²=9x⁴y⁶z²
2. (2m³n⁻⁴)³=8m⁹n⁻¹²
Step-by-step explanation:
Both questions require knowledge of two rules of indices/powers:
(xy)ᵃ=xᵃyᵃ (when numbers multiplied by each other are put to a power, that is equal to the product of each number to that power)
(xᵃ)ᵇ=xᵃᵇ (when a number to a power is put to another power, that is equal to the number to the power of the product of the powers)
1.
(3x²y³z)²
=(3²)(x²)²(y³)²(z²)
=(9)(x²⁽²⁾)(y³⁽²⁾)(z²)
=9x⁴y⁶z²
2.
(2m³n⁻⁴)³
=(2³)(m³)³(n⁻⁴)³
=(8)(m³⁽³⁾)(n⁻⁴⁽³⁾)
=8m⁹n⁻¹²
Hope this helps! :D
Answer:

Step-by-step explanation:
5 x 2/3=3.333333333...
and 3.3333333...
is also equal to 3 1/3
Answer:
just make an account
