The angles are the same magnitude so set them equal to each other and solve for x.
15x = 12x + 15
3x = 15
x = 5
Then plug 5 back into one of the angles.
12(5) + 15 = 75
ANSWER: 75°
We are given the current market price that is <span>$1,200 and we are asked in the problem to compute the target cost if one wishes to gain a 30% profit. In this case, we have to minimize the cost to achieve the profit desired. Then,
1.3 y = 1200
where y is the target cost
y = $923.08
