Answer:A,D
Explanation:
Option a:
Sodium has charge 
Hydroxide has charge
.
So,sodium hydroxide is balanced.
Option b:
Magnesium has charge 
Two sulphates has a charge of
.
So,magnesium sulphate is not balanced.
Option c:
Magnesium has charge 
Two hydroxides have a charge of
.
So,magnesium hydroxide is balanced.
Option d:
Sodium has charge 
Sulphate has charge
.
So,sodium sulphate is not balanced.
Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse.
The triangles are similar (right triangles which share an angle (A), so...
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2
