In the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
In the first diagram:
The sum of the 5k + 20 and 7k + 40 is 180
5k + 20 + 7k + 40 = 180
12k + 60 = 180
12k = 180 -60
12k = 120
k = 10
In the second diagram:
The sum of the two interior angles is equal to the exterior angle.
40 + 12k + 10 = 8k + 80
4k = 30
k = 30/4 = 15/2
Thus, in the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.

<h3>What is permutation?</h3>
The formula for permutation is given as:
Permutation = 
Where:
- n is the total number of objects = 9
- r is the number selected = 3
Substitute into the formula
Permutation = 
P( 9, 3) = 
P( 9, 3) = 
P( 9, 3) = 504 ways
Thus, the number of ways of she can do it is 504 ways
