Answer:

Step-by-step explanation:
We are given the following in the question:

We have to prove:

Proof:

we can write:

Hence, the two triangle are congruent by SAS congruency rule.

The attached image shows the two triangle.
Answer:
k = ½
Equation => 
Step-by-step explanation:
Constant of proportionality (k) = y/x
Using a point on the graph, (6, 3),
k = y/x = 3/6 = ½
k = ½
Equation of the line:
Plug in the value of k into
(slope-intercept form of equation for proportional relationship)
Thus:

Perimeter = 2(length + width)
16.8 = 2(3.6 + width)
3.6 + width = 16.8/2 = 8.4
width = 8.4 - 3.6 = 4.8 in
