I believe it's the same as adding 8+3, but you add the negative sign to your answer
so 8+3 = (-?)

Given: angle = 25°, hypotenuse = 100, opposite = ???


Answer:
B. the more inelastic is the demand for the final product.
Explanation:
Inelastic demand occurs when demand rises by a lower percentage as compared to the percentage of the price drop.
Take for instance, if price drops by 10% and then demand only rises by 4%.
Now, the derived demand curve for a product component will be more inelastic when there's more rises by lower percentages of the final product than price drop. The more inelastic the demand for a product is, the more inelastic the demand derive curve will be.
