In Euclidean geometry, two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling, possibly with additional translation, rotation and reflection so figure A and B are similar.
First step is finding the ratio, the a:b ratio is: 10/12.5=8/10=4/5
A:B=>4:5
16:x = 4:5
So x=20
Answer:
22
Step-by-step explanation:
22 - 19 = 3
3 times -6 = -18

Answer:
A, B, D, and i think F
Step-by-step explanation:
im not sure of F, though.
Refer to the diagram shown below.
The free body diagram of book y indicates:
a weight of 5 N from book z, and a reaction of 5 N on book z;
a weight of 10 N acting on book x, and a reaction of 10 N from book x
The net downward force on book y is
5 + 10 - 10 = 5 n.
Answer: 5 N, downward.
