Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.
Where i is the vertical component and j is the horizontal component
Then u + v is
Answer:
27 ft
Step-by-step explanation:
Given: A garden in the shape of a 45º-45º-90º triangle.
Area of triangle= 32 ft²
As given dimension of triangle, we understand that it is a right angle and triangle and since two angles are equal, therefore two sides of triangle are also equal.
∴ Base and height will be equal.
Assuming base is also as "h"
Now, finding the length of base and height by using area of triangle formula.
Area of triangle=
⇒
Multiplying both side by 2
⇒
Square rooting both side, remember; √a²= a
⇒
∴ h= 8 feet
Hence, both base and height of right angle triangle is 8 feet.
Next, finding total fencing required to enclose the garden.
Perimeter of garden is equal to the amount of fencing required by Adaline.
Therefore, finding the length of hypotenous of triangle too.
Using pythogorean theoram.
, where a is the height and b is the base of triangle.
⇒
⇒
Square rooting both side
⇒
∴ h= 11.3 feet
Perimeter of garden=
⇒ Perimeter of garden=
Hence, 27 feet fencing is required to enclose the garden.
