Answer:
Step-by-step explanation:
Since there exists a scalar
λ
λ
(namely
λ=a⋅b
λ=a⋅b
) such that
b=λa
b=λa
, the directions of the two vertices are the same (they are collinear). This implies that
|a⋅b|=|a||b|
|a⋅b|=|a||b|
.
So,
|a|=|(a⋅b)b|=|a||b||b|
|a|=|(a⋅b)b|=|a||b||b|
which implies that
|b|=1
|b|=1
Answer:
x=5
Step-by-step explanation:
x is the length of the line segment from the center to the boderline of circle. So x=5
Neither?
i dont see any other choice but if im wrong please tell me
Answer:
B
Step-by-step explanation:
It's probably B. Using the steps B has will very possibly obtain the figure in Pentagon B.
H= 92 and h and f equal the same cuz they’re congruent (i think is the right term) so 5x+4=92 so x would be 17.6
