If a plane goes 2000m in 10 seconds - what is it's speed?

200m

Step-by-step explanation:

The formula for speed is:

Speed= Distance/Time

So time to solve:

speed=2000/10

          =200

speed=200

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
