Ответ:
1. It is a right triangle, therefore one angle is equivalent to 90°.
2. We can solve for the measurement of the other leg using the Pythagorean theorem c²=a²+b².
3. We can use SOH CAH TOA theorem in solving the other unknowns.

step-by-step explanation:
the two cars meet at: t = 5 hours
car a leaves at: t = 0
car b leaves at: t = 4.5 hours, so it only travels for 0.5 hours
car b travels 150 km
d = distance from a to b
therefore, car a travels: d – 150 km
150 = (vь) • (0.5) time of travel = 0.5 hours
vь = 300 km/h speed of car b
va = vь – 10
va = 300 – 10
va = 290 km/h speed of car a
d – 150 = (va) • t
d – 150 = (290) • 5
d = 1600 km
