Answer:
B. 2 in.
Step-by-step explanation:
First, put the two perimeters together to form a fraction.
192/48, which can simplify to 4/1
Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

Now, cross multiply. (multiply 1 and 8, 4 and x.)

Now, solve.
x=2 inches.
53,278 can be written as:
50,000 + 3,000 + 200 + 70 + 8
Answer:
0.8660
Step-by-step explanation:
cosine theta = -1/2
theta = cosinearctan(-0.5)
theta = 120
sine4theta = sine 4(120)
= sine480
= 0.8660
