A fluid initially at 100◦C is placed outside on a day when the temperature is −10◦C, and the temperature of the fluid drops 20◦C in one minute. Find the temperature T(t) of the fluid for t > 0.

Temperature drops to -10 deg C after 5.5 minutes and remains at that temperature.

Step-by-step explanation:

∠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.
