A quadrilateral I believe.
Answer:
B -⅓
Step-by-step explanation:
sinx = -3/5
Adjacent² = 5² - 3² = 16
Adjacent = 4
tan(x) = -3/4
-¾ = 2tan(½x)/[1 - tan²(½x)]
-3 + 3tan²(½x) = 8tan(½x)
3tan²(½x) - 8tan(½x) - 3 = 0
tan(½x) = 3, -⅓
Answer:

Step-by-step explanation:
Given

Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x

Write

Multiply
by 

Subtract from 125x^3 - 8
i.e.

Step 2:
Divide 50x^2 by 5x

Write
at the top
Multiply
by 

Subtract from 50x^2 - 8
i.e.

Step 3:
Divide 20x by 5x

Write
at the top
Multiply
by 

Subtract from 20x - 8
i.e.
