Answer:
C
Step-by-step explanation:
The 2 triangles are similar (AA postulate ), thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
14x = 98 ( divide both sides by 14 )
x = 7 → C
Answer:
0.6
Step-by-step explanation:
Given:
Length of first vector = 2 meters
Length of second vector = 4 meters
To find:
The vector which has a greater magnitude.
Solution:
We know that, magnitude of a vector represents the length of it.
The first vector that is 2 meters long has a magnitude 2.
The second vector that is 4 meters long has a magnitude 4.
Clearly, 4 is greater that 2, i.e., 4 > 2. So, magnitude of second vector is greater.
Therefore, the vector that is 4 meters long has greater magnitude.
r/v + a = 5
subtract a from both sides
r/v = 5-a
multiply by v on both sides
r = v*(5-a)
