Answer:
Step-by-step explanation:
Hi!
So, a radical is basically a fractional power.
Square roots are numbers to the 1/2.
For example, the square root of 4 is just , or 2.
So for cube root, the 1/2 changes to a 1/3.
This can then be rewritten as
or
Answer:
72
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = × d₁ × d₂ (d₁ and d₂ are the diagonals )
The diagonals bisect each other at right angles
d₁ = 2 × 6 = 12
Use the tangent ration in the upper left right triangle and the exact value
tan60° =
tan60° = =
=
( multiply both sides by 6 )
opp = 6 , then
d₂ = 2 × 6 = 12
Thus
A = × 12 × 12
= 6 × 12
= 72
