Answer:

20

Step-by-step explanation:

Answer:

∠TRS and ∠VRW equal because they are opposed by the vertex

x+40 = 3x

x-3x=-40

-2x=-40

x= 40/2 = 20°

∠TRS = x+40 =20+40=60°

∠VRW = 3x= 20*3 =60°

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units

Answers

we know that

The volume of a solid right pyramid with a square base is equal to

V=(1)/(3)*[ area\ of\ the\ base]*height

area of the base is the area of a square

area\ of\ the\ base=y^(2)\ units^(2)\nV=v\ units^(3)

Substitute the values in the formula of volume

v=(1)/(3)*[ y^(2)]*height

solve for the height

v=(1)/(3)*[ y^(2)]*height\n \nheight=(3v)/(y^(2))\ units

therefore

the answer is

height=(3v)/(y^(2))\ units

3v/y² units

Further explanation

Given:

  • The volume of a solid right pyramid with a square base is v units³
  • The length of the base edge is y units.

Question:

Which an expression represents the height of the pyramid?

The Process:

We will solve the problem of a geometric solid.

Let us recall the formula of volume of a right pyramid:

\boxed{ \ V = (1)/(3) * base \ area * height \ }

Because the base is square, we use the formula for square area, i.e., side times side.

Let us find out the height of the pyramid.

\boxed{ \ Height = (3v)/(y * y) \ }

Thus, an expression represents the height of the pyramid is\boxed{\boxed{ \ (3v)/(y^2) \ }} units

Area of triangle is, 351. 39 cm²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

All the sides of triangles are,

⇒ 30 cm, 30 cm, and 26 cm

We know that;

⇒ Area of triangle = √ s (s - a) (s - b) (s - c)

Where, 's' is the semi perimeter of the triangle, and a, b and c are three sides of triangle.

Here, Sides are,

⇒ a = 30

⇒ b = 30

⇒ c = 26

Hence, We get;

⇒ s = (a + b + c) / 2

⇒ s = (30 + 30 + 26) / 2

⇒ s = 86 / 2

⇒ s = 43 cm

So, The area of triangle is,

⇒ Area of triangle = √ s (s - a) (s - b) (s - c)

⇒ Area of triangle = √ 43 (43 - 30) (43 - 30) (43 - 26)

⇒ Area of triangle = √ 43 × 13 × 13 × 17

⇒ Area of triangle = 13 √ 731

⇒ Area of triangle = 13 × 27.03

⇒ Area of triangle = 351. 39 cm²

Answer:

351.48cm²

Step-by-step explanation:

Heron’s Formula

Find half the perimeter (30+30+26)/2=43

It’s the square root of each side subtracted from 43, multiplied together, times 43.

√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²
