Answer:
Part A) Use the identity 
Part B) 
Step-by-step explanation:
we know that
----> by trigonometric identity
we have

substitute in the expression above

solve for tan(A)



square root both sides

Remember that Angle A terminates in quadrant IV
so
The value of tan(A) is negative

<em>Find the value of cot(A)</em>
we know that
----> is the reciprocal
therefore

simplify

Answer:x=−9
Step-by-step explanation:
Apply the distributive property.
3 x + 3 ⋅ 1 − 2 x = − 6
Multiply 3 by 1
.
3 x + 3 − 2 x = − 6
Subtract 2x from 3x.
x + 3 = − 6
Move all terms not containing x to the right side of the equation.
Subtract 3 from both sides of the equation.
x = − 6 − 3
Subtract 3 from − 6 .
x = − 9
