Answer:
5 km
Step-by-step explanation:
From. The question, the triangle formed us a right angled triangle,
h km directly from starting point is the hypotenus, h :
Hypotenus = sqrt(opposite² + Adjacent²)
h = sqrt(4² + 3²)
h = sqrt(16 + 9)
h = sqrt(25)
h = 5 km
The <em>correct answer</em> is:
B) the point of concurrency of the perpendicular bisectors of the sides of the triangle
Explanation:
The definition of circumcenter is "the point of intersection of the perpendicular bisectors of a triangle."
To construct the circumcenter, we first construct the perpendicular bisector of each side of the triangle. Once we have these three lines, we find their point of intersection; this is the circumcenter.
Answer:they would meet after 4.5 hours
Step-by-step explanation:
At the point where they will both meet, they would have covered a total distance of 540 miles.
Let t represent the time it will take the car and the truck to meet.
Distance = speed × time
The car drives at a speed of 65 miles per hour. Distance covered by the car in t hours would be
65 × t = 65t
The truck travels at a speed of 55 miles per hour.
Distance covered by the truck in t hours would be
55 × t = 55t
Therefore,. 65t + 55t = 540
120t = 540
t = 540/120 = 4.5 hours
Multiply 80 miles by 4 hours to get 320 miles for 4 hours.
