Answer: Your classmate incorrectly identified the sides that are proportional in the side-splitter theorem.
In this theorem, the segments formed on the traversal are proportional. However, in the diagram your friend is trying to prove that segments on the parallel lines are proportional. If he wanted to do that, he would need to have a different plan.
No.
Because the angles would equal 170. Every triangle MUST have the interior angles of 180 degrees.
Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = 
It is given that per foot cost is $2.
Total cost of the ribbon = 
<em>$40 </em>will be the total cost of the ribbon.
To solve this problem we first call x = number of action figures, y = number of dolles. A system of two equations with two unknowns must be made to describe the problem. The system is the following:
(x + 1) + y = 13
1/2 * x = y.
Then solving the system we have that x = 8 and y = 4.
Since we know that the number of action figures is twice as many dolls plus one, then x = 8 + 1 = 9.
Thus,
dollos = 4
action figures = 9
