Answer:
Yes they are similar.
There are three similarity criteria for triangles.
The first one (AAA) , your case, says that two triangles are similar if their corresponding angles are equal.
The second one (SAS) says that two triangles are similar if two sides have lengths in the same ratio and the angles that are included in these two sides are equal.
The third one (SSS) says that two triangles are similar of all of their sides have lengths in the same ratio.
About the first criteria, you actually need only two corresponding angles to be the same, because the third will always be the difference between 180° and the two angles.
Remember that you CANNOT exceed 180° for the sum of the three angles of a triangle.
And remember also that similarity involves correspondence in sides and angles. Two triangles, with same angles, but mirrored, are not similar!

Answer:
Part A) The graph in the attached figure
Part B) see the explanation
Step-by-step explanation:
Part A) Graph the function
we have the quadratic function
This is a vertical parabola open upward
The vertex is a minimum
using a graphing tool
The graph in the attached figure
Part B) What are the values of a, b and c?
we know that
The values of a and b represent the x-intercepts of the quadratic equation
The x-intercepts are
(-2,0) and (6,0)
so
Find the value of c
we know that
The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots
so
The value of c is equal to
substitute the given values
see the attached figure
A I think I’m sorry if I’m wrong haven’t done this in a while
Answer : C
the total commission (c) a sales associate receives if he sells 15 laptop computers (l)
Total commission = number of laptops * commission for each laptop
Total commission is c
number of laptops is 15
commission for laptop is l
C = 15 * I
So c= 15l
the commission for selling each computer is $39.95
c= 15l
c = 15 * 39.95 = 599.25
