When morgan solved this system using the elimination method, she added the equations together and got the equation 4y=16 then she solved that equation and got y=4 . then she submitted 4 in the first equation for y and solved for x . she got x=4 . the point (4,4) is not the correct solution . state in a complete sentence where she made her first mistake . what is the correct solution to the system show your work in the space provides 2x+3y=20 -2x+y=4

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

can you take a photo of the screen?

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
