Answer:
There are two types of similar triangle problems; these are problems that require you to prove whether a given set of triangles are similar and those that require you to calculate the missing angles and side lengths of similar triangles. Subtract both sides by 130°. Hence; By Angle-Angle (AA) rule, ΔPQR~ΔXYZ.
Step-by-step explanation:

The graph of g(x) is stretched vertically by a factor of 1/3.
Assuming the ratio of 4:5 represents the ratio of width:length then we can set up a simple proportion to find the length...

L = 5(28)÷4
L = 35
Now we can find the perimeter and area of the rectangle:
A = LW
A = 28(35) = 980
P = 2L + 2W
P = 2(35) + 2(28) = 126
