Which of the following are valid names for the given triangle? check all that apply.

A, D and E are correct options.

Step-by-step explanation:

We are given,

The vertices of the triangle are A, X and T.

While writing the names of a triangle, only the vertices are used.

So, we have that the possible names of the given triangle are,

ΔTAX        ΔATX         ΔXAT

ΔTXA        ΔAXT         ΔXTA

Then, according to the options, the valid names for the triangle are,

A. ΔTAX

D. ΔXTA

E. ΔAXT

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
