In similar figures, the angle measures are the same but the side lengths are different. So in #4, x = 42. Since all the angles of a quadrilateral added up equal 360, then y is 360-90-90-42=138. For number 5, make sure you match up the sides correctly in your ratio: 
. You could cross multiply to get 4x=16, and x = 4, or you could just realize that reducing 4/8 will give you 2/4 and x = 4. Going back to the idea that in similar shapes corresponding angles are the same measure, x in #6 is 63
Hi there! The answer is 30.
We need to use PEMDAS to simplify.
P = parenthesis
E = Exponents
M = Multiply
D = Dividing
A = Adding
S = Subtracting
First find the exponents inside the middlest parenthesis.
Now add inside the parenthesis.
Multiply inside the parenthesis that are left.
Divide inside the parenthesis
Add inside the parenthesis.
Multiply.
~ Hope this helps you!
