How many two digit whole numbers can be written as the sum of two different single digit whole numbers? lots of points, and will give brainliest! !

8

Step-by-step explanation:

possible sum of two different single digit whole numbers is 0+1=1 to 8+9=17

if the sum must have two digits, the range becomes 10 to 17

so ans is 8

∠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.
