Answer:

3.92 approximately 4

Step-by-step explanation:

let us first find angle at F

40⁰+50⁰+F= 180 (sum of angles in a triangle)

90⁰+F= 180⁰

F= 180⁰-90⁰

F = 90⁰

using sine rule

3/sin 50 = x/sin 90

3/0.7660= x/ 1

0.7660x=3

x= 3/0.7660

x= 3.92 approximately 4

What is 3(2x-4)=6(x-2)<br> with solving steps?

dedylja [7]

Answer:

true for all x

Step-by-step explanation:

3(2x-4)=6(x-2)

Distribute

6x - 12 = 6x -12

Subtract 6x from each side

6x-12 -6x = 6x-12-6x

-12 =-12

Since this is always true, there are infinite solutions
