Answer:

>regular triangle, we call equilateral triangles regular polygons.

>isosceles, as an equilaterial triangle is a specific type of isosceles due to more than one side being of equal length and angle.

>equilateral, where all sides and angles are the same.

>acute, as all 3 angles are less than 90

>equiangular. equilateral triangles are also described as equiangular.

Step-by-step explanation:

Just the five ways above can describe the polygon shown, as the angles of a scalene triangle are unequal. as are their sides, equilaterial have same sides and angles. Obtuse have angles larger than 90deg less than 180 deg.

Whilst irregular are triangles and shapes that have uneven sides and are not right or isosceles.

Right triangles have one angle that is exactly 90 deg.

N/2+5=3

move +5 to the other side

sign changes from +5 to -5

N/2+5-5= 3-5

N/2= -2

Mutiply both sides by 2/1

N/2*2/1 - Cross out 2 and 2 , divide by 2 then becomes N

-2(2)/1= -4/1= -4

N= -4

Answer : N= -4

Carol is going to make a wooden pyramid and then paint it. She drew the net of a square pyramid as shown below to help her plan

rodikova [14]

The given pyramid's total surface area is 3. 24.0 square feet.

Step-by-step explanation:

Step 1:

To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.

There are 3 triangles and 1 square in the figure.

Step 2:

All the triangles are similar.

The surface area of a triangle = $\frac{1}{2} (baselength)(height).$

The similar triangles have a base length of 3 feet and a height of 2.5 feet.

The surface area of 1 similar triangle = $\frac{1}{2} (3)(2.5)= 3.75$ square feet.

The surface area for all the similar triangles = $3.75 (4) = 15$ square feet.

Step 3:

The surface area of a square is the square of its side length. The square has a side length of 3 feet.

The surface area of the square = $a^{2} = 3^{2} =9$ square feet.

Step 4:

To calculate the total surface area we sum up all the individual surface area.

The total surface area = $15 + 9 = 24$ square feet which is the third option.
