Is this what you mean or did I get mixed up?
Answer:
12°
Step-by-step explanation:
Sum of interior angles of the triangle is 180°:
m∠A + m∠B + m∠C = 180°
3x + 28° + 5x + 52° + 2x - 10° = 180°
10x + 70° = 180°
10x = 110°
x = 11°
Find the measure of angle C:
m∠C = 2x - 10° = 2(11°) - 10° = 22° - 10° = 12°
X = [-b +- sqrt(b^2-4ac)]/2a
We can form a ratio equation. the ratio would be the amount of original apples to the cost versus the new amount of apples and new cost. we know all amounts except original cost.
pounds/cost = new pounds/new cost
9/x = (3/4)9 / 15
9/x = (27/4) / 15
9/x = 27/60
9/x = 9/20
cross multiply
9x = 180
x = 20
