Answer:
Using Pyhagoras Theorem for the right-angled triangle ABO,
h² = 12² + 16² = 400.
∴ The length of the side of the rhombus is 20 cm.
★½×24×32 = 20×h
∴ h= 19.2 cm.
let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.
cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.

Answer:
Sry if it is wrong..........
10 to the 4th power equals 10,000 and when you times 10,000×7 it equals 70,000 so you answer to that problem would be 7
