What is the lengths of all 3?

AB=15

AC=15 as an isosceles triangle base arm

BC=4

Step-by-step explanation:

TO find value of (X)

take bath base arm

2x-1=X+7

2x-x=7+1

X=8

now

put value of (X)

AB= X+7= 8+7=15

AC=15 as an isosceles triangle base arm because both arm should be equal

AC=2X-1=2*8-1=15

BC= X-4=8-4=4

∠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.

probability for j is 1/4

while

a is 1/6
