X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.
So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.
Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)
That makes 14/6=X/3. When we cross multiply, we find that x=7.

Answer:
236 cm²
Step-by-step explanation:
Height of an equilateral triangle (h) = √3 /2 (l)
l = side of the equilateral triangle.
h = √3 /2 (15)
In an equilateral triangle the orthocenter, centroid, circumcenter and incenter are in the same spot
The center of the circle is the centroid and height match with the median. The radius of the circumcircle is equal to two thirds the height.
Formula for the Radius of the circumcircle = 2/3 h
= 2/3 x √3 /2 (15)
= 5 √3 cm (=radius)
Area of the circle = πr^
= 3.14 x( 5 √3 ) ^
=3.14 x(25*3)
=3.14 x 75
=235.5
=236 cm²
X = 4/7 = 0.571 I believe so
