Step-by-step explanation:
The pizza chain has 5 different topings.
Number of different pizzas = 2⁵ = 32.
We have 2^n >= 1000.
Since 2⁹ = 512 and 2¹⁰ = 1024,
the minimum number of toppings is 10.
We have two sides and one angle opposite to one of the known sides.
Begin with applying the Law of Sines to find angle A:
= <span>
Then, solve for sin A:
</span>sin A =
Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17
We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
