Answer:

Step-by-step explanation:

8 would be the common denominator, so you would multiply the 1/2 by 4/4 to get 4/8, and if you needed to add, 4/8 + 1/8 is 5/8

1. Factor and simplify: cos² xcsc² x-cos²xcot² x

Vera_Pavlovna [14]

Answer:

Cos² x

Step-by-step explanation:

<h3>Trigonometry:</h3>

$\sf Cos^2 \ x *Csc^2 \ x-Cos^2 \ x *Cot^2 \ x = Cos^2 \ x (Csc^2 \ x - Cot^2 \ x)$

$\sf = Cos^2 \ x \left(\dfrac{1}{Sin^2 \ x} - \dfrac{Cos^2 \ x}{Sin^2 \ x}\right)\\\\= Cos^2 \ x \left(\dfrac{1-Cos^2 \ x}{Sin^2 \ x}\right)\\\\\boxed{\bf Indentity: \ 1 - Cos^2 \ x = Sin^2 \ x}\\\\\\= Cos^2 \ x \left(\dfrac{Sin^2 \ x}{Sin^2 \ x}\right)\\\\= Cos^2 \ x$

40 points help me please

Alinara [238K]

Answer:

x=60

Step-by-step explanation:

(1/6)(x+6)=11

Multiply both sides by six:

(6)(1/6)(x+6)=11(6)

x+6=66

Take six from both sides:

x+6-6=66-6

x=60
