They're trying to trick you with √2. Remember in the 30/60/90 triangle the sides are in ratio 1:√3:2, with the "1" opposite the 30 degrees.
Here we have
1:√3:2 = 6√2:x:hypotenuse
or
x/(6√2) = √3/ 1
x = 6√2×√3 = 6√6
Answer: AC=6√6
Answer:
28.26
Step-by-step explanation:
The formula for calculating diameter is π<em>d</em> (pi times the diameter), so 3.14 times 9 is 28.26.
by pythagorean formula, the last side is √(61)
by cos rule
cos A

A = 39.81
