Answer:
23°
Step-by-step explanation:
Let the interior angles of ΔABC be referenced by A, B, and C. The definition of point D means that ΔDAB is an isosceles triangle, so we have the relations ...
A + B + 118 = 180 . . . . interior angles of ΔABC
A = B +16 . . . . . . . . . . base angles of ΔDAB
Using the expression for A in the second equation to substitute into the first equation, we get ...
(B+16) +B +118 = 180
2B + 134 = 180 . . . . . collect terms
2B = 46 . . . . . . . . . . . subtract 134
B = 23 . . . . . . . . . . . . divide by 2
m∠ABC = 23°

Here is the solution of the given problem above:
The first thing we should do is to multiply 50 and 13 3/4
13 3/4 is equivalent to 13.75 .
So, we then multiply
50 x 13.75 and we get 687.50.
so, $687.50 was the amount spent on the stock.
Now, lets find out how much they sold them for:
What we do is multiply 12 and 50
50 x 12 would be 600
We can find out the loss by subtracting
$687.50 - $600 and that gives us $ 87.50.
Therefore, the amount that is loss in selling is $87.50. The correct answer would be option B. Hope this answer helps.
