Find the value of x.

Mathematics

Anvisha [2.4K]2 years ago
6 0

Answer:

x = 36

Step-by-step explanation:

The angles of a trapezoid add up to 360, so add x, 4x, 3x, 2x to get 10x

10x = 360

360/10 = 36

Therefore, x = 36

(I am assuming the ()0 is a makeshift degree symbol-)

the sum of all interior angles in a polygon is

180( n - 2)

n = number of sides

now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.

360=x+4x+3x+2x\implies 360=10x\implies \cfrac{360}{10}=x\implies 36=x

What is the total surface area of the rectangular pyramid below
Novosadov [1.4K]

Answer:

<h2>S.A. = 225 ft²</h2>

Step-by-step explanation:

We have

the rectangle 12ft × 6ft

two triangles with the base b = 12ft and the height h = 8ft

two triangles with the base b = 6ft and the height h = 9.5ft.

The formula of an area of a rectangle l × w:

A=lw

Substitute:

A_1=(12)(6)=72\ dt^2

The formula of an area of a triangle:

A=\dfrac{bh}{2}

Substitute:

A_2=\dfrac{(12)(8)}{2}=48\ ft^2

A_3=\dfrac{(6)(9.5)}{2}=28.5\ ft^2

The Surface Area:

S.A.=A_1+2A_2+2A_3

Substitute:

S.A.=72+2(48)+2(28.5)=225\ ft^2
