A projectile is launched from ground level with an initial velocity of V0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s= - 161? + vot. Find the time(s) that the projectile will (a) reach a height of 400 ft and (b) return to the ground when vo is 128 feet per second.
(a) Find the time(s) that the projectile will reach a height of 400 ft when Vo = 128 feet per second.

∠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.
