Answer:
BD = 14
Step-by-step explanation:
The Pythagorean theorem can be used to find the lengths of CD and BC.
CD² +12² = 13²
CD = √(169 -144) = √25 = 5
__
BC² +12² = 15²
BC = √(225 -144) = √81 = 9
__
The length BD is then ...
BD = BC +CD
BD = 9 + 5 = 14
The length of side BD is 14 units.
Answer:
See below
Step-by-step explanation:
We have to show that is an unit vector.
To show this, we will find the modulus of and if its value is 1, it will be a unit vector.
So,
Thus, is a unit vector.
