You can answer this problem using the midpoint formula, but we can work out the 4th vertex by just logically thinking it through by first drawing out the rhombus on an x-y coordinate plane. I wrote the answer out on paper since it is easier than typing. Let me know if you have any questions.

Answer:
D
Step-by-step explanation:
First, find the slope of BC :
⇒ m (BC) = -1 - 5 / -3 - 5
⇒ m (BC) = -6/-8
⇒ m (BC) = <u>3/4</u>
Now, since AD is the altitude of BC, we can say the altitude is perpendicular to BC.
Hence, the slope of a perpendicular line is equal to the negative reciprocal of the original line.
⇒ m (AD) = - (1/m(BC))
⇒ m (AD) = - (1/(3/4))
⇒ m (AD) = -4/3
I would have to say (B) ! Good Luck :D
Answer:
b=5V2
Step-by-step explanation:
Area =31 1/4 = b*12.5 sin45/2=b*12.5*V2/2* 1/2=12.5V2/4 *b
(31*4+1)/4=125/4
so 125/4= 12.5V2*b/4
12.5V2*b=125
b=125/12.5V2=10/V2=10V2/2=5V2
