Answer:
If the model is 3 inches tall, the model bookcase should be <em>2 inches</em> wide.
Step-by-step explanation:
When using similar figures, set up a proportion of the model measurements to the actual measurements:

Then cross multiply and solve for x:

Answer:
x ≈ 11.7
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° =
=
( multiply both sides by 13 )
13 × cos26° = x , then
x ≈ 11.7 ( to the nearest tenth )
Answer:
the first one since it shows all the lines being equal and therefore making the angles equal
X-3/8=-1/4
+3/8
x=-1/4+3/8
make both bottom numbers the same so you are able to add them
-1/4×2/2= -2/8
x=-2/8+3/8
x=1/8
