Step-by-step explanation:
The altitude of an equilateral triangle:
h = s √3 / 2, where s is the length of one side of the triangle.
s √3 /2 = 7 √ 3 / : √3

Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Now, we will use "Substitution Method" to find the values of x and y:
Put the value of x in first equation i.e.
Now, we use the value of y in equation (3),
Hence, values of (x,y) is (4,1).
Therefore, First Option is correct.
