If i’m correct it’s your scratch account! about you is that you speak spanish, love good old music, horses and farm life, etc.
If the radius is the radius of the inscribed circle then the side of the triangle = radius * 6 / (sq root(3))side = 20.785tan 60 = height / half-sideheight = tan 60 * half-sideheight = 1.732 * 10.3925 height = 17.99981 triangle area = .5*side*heighttriangle area = 10.3925 * 17.99981triangle area = 187.06
If the radius is the radius of the circumscribed circle then the side of the triangle = radius *3 / (sq root(3))side of the triangle = 6 * 3 / sq root(3)side of the triangle = 10.3923048454 half-side = 5.1961524227 height = tan 60 * half-sideheight = 1.732 * 5.196height = 8.9997
triangle area = .5*side*heighttriangle area = 5.196 * 8.9997triangle area = 46.764
Hope this helps!
The lines are perpendicular if their slopes are negative reciprocal of the other.
Since 9/2 is just a reciprocal and not the NEGATIVE reciprocal of 2/9, the lines are NOT perpendicular.
Answer:
in a parallelogram .......the sum.of adjacent angles is 180
11x-10+80=180
11x=110
x=10
