We can break √10 into √2 • √5, and √8 into √2 • √4, or, simplifying √4 to 2, 2 • √2. Our expression now becomes
(√2 • √5) / (4 • 2 • √2)
Cancelling the √2 in the numerator and denominator gets us
√5/(4 • 2), or √5/8.
X=22. The supplementary angle is 90°, so the 66° angle, plus (x+2) has to add up to 90° too.
Answer: The solution is 
Step-by-step explanation:
since we have given that
we need to solve it using area models:
As we know that "In fractions, division is changed into multiplication by reciprocating the next term to make it possible to solve":
So, It turns into model of area "Area of rectangle "
Now, verifying by using numerical operations only.
Hence, verified.
