Which set of angles can form a triangle

Any set of three angles that add up to 180 degrees can form a triangle.

Step-by-step explanation:

A triangle is a polygon formed by three segments which each line intersects with the other lines.

And every triangle has properties that always have to fulfill but the most important one to know how to form a triangle is:

The angles of the triangle always sum to 180 degrees.

          Example: Angle A + Angle B + Angle C = 180°.

                    So, 50 + 30 + 100 = 180°.

           Therefore the angles has to be less than 180 degrees.

So, any set of three angles that add up to 180 degrees can form a triangle.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
