It depends how you name the sides of triangle.
Look at picture at the result.

$cos\alpha=\frac{12}{13}\\
cos\beta=\frac{5}{13}$

PS. Sorry for my terrible drawing but I did it as fast as possible :)

Expand the following 5(2x-4)

Yuliya22 [10]

Answer:

x= 2

Step-by-step explanation:

5*2= 10 then add the x at the end

5*4=20

then you divide both sides by 10

(10x/10)- (20/10)

x= 2

or if your rewriting it then:

(5*2x)- (5*4)=?

Hope this helped :D
