Answer:
$1.6
Step-by-step explanation:
The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost
Using the concept of cross multiplication we say that if
1.45 is equivalent to $2.32
1 is equivalent to x
Therefore, the company incurs $1.6 for each plug
A linear pair are two given angles whose sum is equal to .
Let the exterior angle be represented by , and the three interior angles of the triangle be represented by , and .
Assume that the vertex angle is the linear pair to the exterior angle .
i.e + = (sum of angles on a straight line)
Thus,
i. + = (sum of two opposite interior angles is equal to an exterior angle)
⇒ = -
Also,
= -
But,
+ + = (sum of angles in a triangle)
⇒ = - ( + )
and
+ = -
ii. + + = (sum of angles in a triangle)
= - ( + )
+ =
