Answer:

EF+FG =EG

18 + FG =20

FG = 20-18

FG = 2

x=-2

Step-by-step explanation:

6x-5=-17

Add 5 to both sides of the equation.

6x=-12

Divide both sides by 6 to get x alone.

4:10

24:60

48:120

As long as you multiply or divide both sides of the ratio by the same number, you will have an equivalent ratio.

The inside angles of a 4 sided shape when added together equal 360.

X = 360 - 50-130-120

X = 60 degrees.
