Washing 2 cars and 3 trucks take 130 minutes. washing 2 cars and 5 trucks take 190 minutes. how long does it take to wash one car and one truck? show your work and explain your reasoning in the space provided below.

It takes 30 minutes for 1 truck and 20 minutes for 1 car. Therefore it will take 50 minutes to wash one car and one truck. 190-130= 60. 5 trucks -3trucks = 2 trucks. 60/2= 30 minutes per truck. Then 130- 2 trucks (60 minutes) =40. 40/2(cars)= 20 minutes per car

∠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.
