The given image is a triangle.

Property of triangle:

A triangle has three sides.

A triangle has three angles.

A triangle has three vertices.

To find the sides, angles and vertices of the triangle RST:

Sides of the triangle SRT:

RS, ST and RT

Angles of the triangle RST:

∠A, ∠B and ∠C

Vertices of the triangle RST:

A, B and C

These are sides, angles and vertices of the triangle.

Find the answer given below

Anastasy [175]

Answer:

Surface area = 6l^2

Volume = l^3

If total surface area increased by 2, then the length increased by $\sqrt{2}$

Volume then is increased by ( $\sqrt{2}$ l)^3 = 2 $\sqrt{2}$ l^3

1 :2 $\sqrt{2}$

Which is not an option in the question so this question clearly has a problem.

First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.

Second of all, if the answer is 8:1 the question should be "If each sides of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.

Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled by doubling the height and without changing the length and width" But, then the the shape would no longer be a cube.

Who even wrote this garbage question what.

Using the drawing, what's the vertex of angle 4

pshichka [43]

Using the four points around the drawing, we can see that angle four is connected to the vertex A.

The answer I believe is:
D. Vertex A.

Hope I could help! Have a good one.
