In rectangle $EFGH$, $EH = 3$ and $EF = 4$. Let $M$ be the midpoint of $\overline{EF}$, and let $X$ be a point such that $MH = MX$ and $\angle MHX = 72^\circ$, as shown below. Find $\angle XGH$, in degrees. [asy] unitsize(1 cm); pair A, B, C, D, M, X; A = (0,3); B = (4,3); C = (4,0); D = (0,0); M = (A + B)/2; X = rotate(26,M)*(D); draw(A--B--C--D--cycle); draw(D--M--X--cycle); draw(C--X); label("$E$", A, NW); label("$F$", B, NE); label("$G$", C, SE); label("$H$", D, SW); label("$M$", M, N); label("$X$", X, S); [/asy]

hope this .

answer: 1 and 3

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

$450 i think. hope this ☺
