Hello :> Can someone help please? if you can a brief explanation would be nice. ty !

x = 12. 4¯

(the 4 is supposed to be under the line)

The line sgnifies that the number goes on forever, such as

12.444444444444 and so forth

anyways, youre going to use "cross multiply and divide" which means you multipy the two number on one side top, and the other bottom. Make sure its the one that does have the x!

I multipled 7 * 8 which equals 56, and the leftover number, which is 4.5 is what i divide. When we divide that we get our answer, which is x.

Hope this helped!!

Step-by-step explanation:

x= 12.444

Step-by-step explanation:

The fractions are equal.

7÷4.5= 1.555

8·1.555=12.444

x=12.444

I hope you understand this but if you need further explanation, just tell me :P

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
