Moving with a speed of v km/hour, a train travels the distance between the points a and b, which is 600 km, in t hours. find the formula which describes:

t in terms of v

t=600km/Vkm/h

Step by step explaination:

Step1:Use the formula S=d/t.

We've been given that s=Vkm/h, d=600km and t is not given.

Step2: Substitute in the values

s=d/t

Vkm/h=600km/t

tVkm/h=600km

then make t the subject by dividing both sides by Vkm/h

finally, the equation will be t=600km/Vkm/h as our final answer.

PLEASE MARK AS BRAINLIEST.

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°
