You use a compass to draw angles and straightedge to draw the shapes.
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be
180° = 2*Base angle + Vertex angle
Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°
Vertex angle = 4(31°) - 6
Vertex angle = 118°
Yvaires directly as x means
y=kx
y varies inversly with z means
y=k/z
therfor
y=(kx^2)/z
k=constant of variation
6=(k9^2)/27
6=(k81)/27
6=3k
divide both sides by 3
2=k
the constant of variation is 2
