Answer:
8x - 5y - 13
Step-by-step explanation:
(6x - 3y - 12) - (2x +2y - 10)
(6x - 3y - 12) - 2x - 2y + 10
6x - 3y - 23 - 2x - 2y + 10
8x - 5y - 13
9*8*7*6*5*4 = 60480. Hope this helps !!!!!!!!!!!!!!!!!!!1
"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.
The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
Step-by-step explanation:
Given,
Perimeter of hockey rink = 570 feet
Width of hockey rink = w
Length of hockey rink = w+115
As a hockey rink is in rectangular shape;
Perimeter of rink = 2(Length + Width)

Dividing both sides by 4

Width of hockey rink = 85 feet
Length of hockey rink = 85+115 = 200 feet
The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
