X=34
34=34
45=45
But because OF this equation the answer is 34
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
Hope this helps!!
Answer:
-3i +9j+3k
Step-by-step explanation:
Given that the vector is represented by the directed line segment with initial point A(1, −4, 1) and terminal point B(−2, 5, 4).
Position vector of A with respect to origin = (1, −4, 1)
position vector of B with respect to origin = (-2,5,4)
AB vector = OB-OA
= (-2-1, 5-(-4),4-1)
= (-3, 9, 3)
Line segment AB is (-3,9,3) or
-3i +9j+3k
Initial point is A and final point is B
Answer: 158.00 km/sec
Step-by-step explanation:
From the information given, we are informed that the plane travels 395 kilometers in 2.5 hours.
The average speed of the plane in km/sec will be calculated as:
= Distance / Time
= 395 / 2.5
= 158.00 km/sec
