Step-by-step explanation:
Given:
Lengths of edges of triangle:
feet
feet
feet
Perimeter of the triangle= Sum of all sides =
feet
On simplifying by adding like terms:
Perimeter of triangle =
feet
Given 
∴ Perimeter of triangle =

= 40 feet
Answer:
See below
Step-by-step explanation:
x = 3 cos (-5pi/3) = 1.5
y = 3 sin (-5pi/3) = 2.598
Which of the following is the domainof the given relation?{(-6, 3), (-4 ,5), (0, 0)}A {0, 4, -6}B {0, 3, 5)C {3, 4, 0}D {-6, -4,
Bas_tet [7]
The domain is the input, which is the x value in the relation (x, y)
Hence the domain in the given relation {(-6, 3), (-4 ,5), (0, 0) is :
{-6, -4, 0}
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.
hope this helps :))
