<u>Ashely have </u><u>56 ways</u><u> to choose from</u>
This question can be solved using a system in mathematics called Permutation and it's in a topic of mathematics called combinatorics.
<h3 /><h3>Permutation</h3>
This is the process of arranging a particular set of data in different ways.
Since Ashely is choosing 3 desserts out of 8 in no specific ways

Where n = total number of ways available
r = total numbers that would be selected.
Data given
Let's substitute these values into the equation.

From the calculation above, Ashley have 56 ways in which can choose 3 dessert from an 8 choice.

We can answer the question above by using the trigonometric functions and the concept of similar triangles.
Given that cos (L) is 4/5. The length of sides PN and NL can be solved. Please see solution below.
4/5 = NL / 15 ; NL = 12
Solving for PN,
PN² + 12² = 15²
The value of PN is 9.
Then, using the concept of similar triangles,
KN/(KN + NL) = PN/ KM
Substituting the known values,
4/(4 + 12) = 9 / KM
The value of KM is 36.
Its the answer 764 so the surface area would be 764
