Answer:


Step-by-step explanation:
Given
See attachment for triangles
Solving (a)

The tan of an angle is:

From the given triangle.


So, we have:

Solving (b)

The cos of an angle is:

From the given triangle.


So, we have:

The answer is C) Saul’s account earned $3,338 more interest than Mark’s account
First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry
1st: group the number
(X2+6x)-9
2nd: use b/2
6/2 = 3 , 3^2= 9
(X2+6x+9)-9-9
(X2 + 3)-18
Vertex is 3,-18 so the symmetry is 3
