In the diagram, kl ≅ nr and jl ≅ mr. what additional information is needed to show δjkl ≅ δmnr by sas? ∠j ≅ ∠m ∠l ≅ ∠r ∠k ≅ ∠n ∠r ≅ ∠k

According to SAS theorem which means Side Angle Side,

The angle which is included between the two sides must be congruent.

Here we are given that

KL = NR

JL = MR

Now in the figure we can clearly see that the angle included between JL & KL is L & the angle included between NR & MR is R.

So for the triangles to be congruent by SAS, angle L must be congruent to angle R.

∠L=∠R

Second option is the right answer.

B

Step-by-step explanation: i just took the quiz

i used to know but i learned it a long time ago sorry

step-by-step explanation:

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
