If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
cos 30 = 9 /h where h = one of the sides of the equilateral triangle
h = 9 / cos 30 = 10.392 inches
Therefore the perimeter of the triangle = 3 * 10.392 = 31.1769 ins
Answer is 31.18 inches to the nearest hundredth.
Answer:
Yes
Step-by-step explanation:
They are proportional by a scale of 1.5
It would be A. because to find out how much 18 eggs would cost you would need to figure out by dividing $1.98 and 8.
hope this helped :)
yes, six times a number of n is 6n the greater than or equal ≥ and y plus two is y + 2
