Answer:
Part a) The ratio of the perimeters is 
Part b) The ratio of the areas is 
Step-by-step explanation:
Part A) What is the value of the ratio (new to original) of the perimeters?
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the new triangle
y-----> the perimeter of the original triangle

we have

substitute

Part B) What is the value of the ratio (new to original) of the areas?
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the new triangle
y-----> the area of the original triangle

we have

substitute

Answer:
808 over 25 as a faraction
Step-by-step explanation
a quarter of 65 is 16 4 over 25
16 4 over 25 times 2 808 over 25 as a fraction
x = 32°
The triangle has 2 equal sides and is therefore isosceles, thus the 2 base angles are also congruent.
The 2 base angles are of size x°
x =
=
= 32
