Answer:
The corresponding side in the smaller figure is 9 cm
Step-by-step explanation:
Notice that you can use proportions to solve this problem:
The ratio from large image to smaller is: Larger/smaller = 4/3.
Therefore use this type of proportions to find the length of the corresponding side to 12 cm in the smaller figure:

Answer:
Step-by-step explanation:
Both of the triangles are special 30-60-90 triangles
and the side lenghts for these angle mesurements are followed : q, q√(3),2q
q is given as 3 from the 9th question
so a = 6 (because it's 2q) and
b = 3
For the 10th question
the side length that sees 30 degrees is 3 which means q = 3 again
and x = 6
y = 3√(3)
Unreduced fractions are fractions that aren't simplified all the way.
Like 2/6.
It can be simplified to 1/3, so it's an unreduced fraction.
8x3 + 10x2 – 8x + 1
