Answer:
x = (√21)/2
Step-by-step explanation:
The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. That means the middle-length side is (√3)/2 times the length of the longest side.
x = (√3)/2·√7

the algebraic expression would be;
x - 6 = x
hope it helped :D
Area=πr^2
Area=π(16)^2
Area≈804.2477 cm^2
I left the number large enough in case you need to round it off to some other decimal place.
