What is the volume??

245 cm³

Step-by-step explanation:

Volume of a triangle = length x width x height / 3

7 x 7 x 15 = 735

735/3 = 245

volume of a triangle =length×width height 3

7×7×15=735

735/3=24

∠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.
