Step-by-step explanation:
<1 = 90 - 32
= 58
bd is a traversal to parallel line ab and dc
<1 = <bdc ( alternate angles) = 58
in right triangle edc
90 - 58 = <3 = 32
<2 = 58
The one of the left isn't too tricky, in the bottom left of it you have 1/2 of 1/4 of the shape, and on the bottom right you have 1/4 of 1/4. Imagine the whole shape was cut up like that bottom right bit into 16 triangles, then you would have three of them shaded (see my diagram).
The one on the right seems like guesswork to me, so I'm sorry if I'm wrong. It look like you just have to use your eyes to work out how much of the bottom half of the shape is shaded: looks like 1/16 to me (i.e. you can draw four of those along and four down, again, see my diagram.) So plus the top half, which is 8/16, you get 9/16.
Answers: left picture: 3/16.
right picture: 9/16.

Price of
Computer(C) + Printer(P) + Scanner (S) = $2543
Price of Computer:
C = 1502 + P
Price of Printer:
P = 123 + S
So Price of computer now becomes:
C = 1502 + 123 + S (Here we replace P with 123 + S)
It is Algebra from here:
C + P + S = 2543
(1502 + 123 + S) + (123 + S) + S = 2543
1748 + 3S = 2543
3S = 2543-1748
3S = 795
S = 795/3
S = 265
C = 1502 + 123 + S
C = 1502 + 123 + 265
C = $1890
