Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° = 
, then
tanf° = 
= 
= 
= ( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
The formula for finding the area of a parallelogram is-
A=b*h Where A=Area b=base length h=height
A=10*4
A=40
37 over 8 or 37/8. I plugged it in on my calculator and it was correct.
To solve/simplify this all you have to do is group like terms (the x^2's with each other, the x's with each other, and the normal numbers, -8)
14x^2-8+5x-6x^2+2x
group the x^2 (add 14x^2 to -6x^2)
8x^2-8+5x+2x
group the x's together (add 5x and 2x together)
8x^2+7x-8
Your answer will be d) 8x^2+7x-8
