Answer:

Below in bold.

Step-by-step explanation:

We have a right triangle here with the hypotenuse = 2 and the legs are 1 and √3.

If tan A > 0 then the opposite side to < A in the triangle is greater than the adjacent so the leg opposite angle A is √3 and the adjacent side = 1.

So cos A = adj/hyp = 1/2.

9 - 4(2x - 1) = 45 please help

ddd [48]

Answer:

$x=-4$

Step-by-step explanation:

$9-4(2x-1)=45$

First, we expand the equation using the distributive rule:

$x(y-z)=xy-xz$

Hence, $9-4*2x-4*-1=45$

Simplify: $9-8x+4=45$

Add like terms:

$13-8x=45$

Subtract 13 from both sides: $-8x=32$

Divide both sides by -8:

$x=-4$
