Answer:
The percentage loss = 10.9375 %
Step-by-step explanation:
Let the cost price = x
Since the marked price is 18.75% above the cost price so the
Marked price = 1.1875 x
When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425
⇒ Marked price × 0.75 = 1425
⇒ Cost price × ( 1.1875 × 0.75 ) = 1425
⇒ Cost price × ( 0.890625 ) = 1425
⇒ Cost price = 1600
Selling price = 1425
So percentage loss = × 100
% Loss = × 100
% Loss = 10.9375 %

Answer:
2
PLZ MARK BRAINLIEST
Step-by-step explanation:
(-8+4) - (3-9) = (-4) - (-6) = -4 + 6 = 2
You know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°
