Answer:
To find the answer consider that this is a right triangle and we can use the tangent function in order to find the value of x
remember the acronym soh cah toa.
to use the tangent function we divide the opposite and adjacent side that is what the oa stands for in toa
setting it up looks like this
tan 72° =
solving for x gives us x= 8×tan 72°
which is about 24.62

Answer:
The salespeople earn for the sale of a suit = $13.
The salespeople earn for the sale of a pair of shoes = $8.
Step-by-step explanation:
Let x be the commission for each suit and y be commission for each pair of shoes.
We have been given that for selling 3 suits and one pair of shoes, Carla has earned $47 in commission. We can represent this information as:
We are also told that for selling 7 suits and 2 pairs of shoes, Benicio has earned $107 in commission. We can represent this information as:
We will use substitution method to solve our system of linear equations. From equation (1) we will get,
Substituting this value in equation (2) we will get,
Upon combining like terms we will get,
Therefore, the salespeople earn $13 for the sale of a suit.
Let us substitute x=13 in equation (1).
Therefore, the salespeople earn $8 for the sale of a pair of shoes.
