Answer:

-52.5 or -53

Step-by-step explanation:

Start by subtracting 18 from both sides. With you get 0.4=-21. Now divide 0.4 into both sides.

Answer:

x=-77.5

Step-by-step explanation:

since we're looking for x,18 must cross the equal sign to become negative.

0.4x=-13-18

0.4x=-31

dividing both side by 0.4,

we have x=-31÷0.4

therefore x= -77.5

**Giving away 20 points**. I need to know the arc length for EF and the area of sector EOF please:) (also plz show work thanks!!
LiRa [457]
Let us for a few seconds nevermind there's a circle at all, so we only really have a triangle by itself.

now, EF = 18, wait a second!  EF is the base of the triangle, and h = 10.725, wait a minute!!  "h" is the height of the triangle.

so, what's the area of a triangle whose base is 18 and has a height of 10.725?  yeap, we knew you'd know that one.

what's the length of the arcEF?  well, we know the central angle of ∡FOE is 80°, well, arc's get their angle measurement from the central angle they're in, so if ∡FOE is 80°, so is arcEF then.
