QUICK! What is the surface area of the triangular prism?

88 ft^2

Step-by-step explanation:

The triangular face is that of an isosceles triangle, where two sides are equal. The formula for the S.A of a triangular prism is:

SA = bh + (s1 + s2 + s3)H

s1 + s2 + s3 are just the sides. This means you are finding perimeter.

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!    

∠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.
