Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20

We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:
For
:
The function for this domain is:

For
:
The function for this domain is:

Where,

Substituting:

For
:
The function for this domain is:
Length=3width-5
(2(x))+(2(3x-5)=46
2x+6x+10=46
8x=56
x=7
width=7 length=16
