If ab = 15, bc = 12, and ca = 8, list the angles of abc in order from smallest to largest.

The list the angles of triangle ABC in order from smallest to largest is ∠B, ∠A and ∠C.

Step-by-step explanation:

Given information: In ΔABC, AB = 15, BC = 12, and CA = 8.

In a triangle, opposite side of the largest angle is largest, opposite side of the medium angle is medium and opposite side of largest angle is largest.

Arrange the sides in ascending order.

The opposite angels of CA, BC and AB are ∠B, ∠A and ∠C respectively.

Therefore the list the angles of triangle ABC in order from smallest to largest is ∠B, ∠A and ∠C.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
