Consecutive angles of a parallelogram are supplementary, therefore:

Angle 3 + 110° = 180°

Subtract 110° from both sides of the equation

Angle 3 + 110° – 110° = 180° – 110°

Angle 3 = 70°

Opposite angles of a parallelogram are congruent, therefore:

Angle 2 = 110°

Angle 1 = Angle 3

Since Angle 3 = 70°

Angle 1 = 70°

Summarily,

Angle 1 = 70°

Angle 2 = 110°

Angle 3 = 70°

How do you find the circumference or a circle with only a diameter?

bogdanovich [222]

To find the circumference of a circle that lists only as a diameter, you would do pi*d so lets say the diameter is 6, you would do pi*6 which would end up giving you 18.84. I hope this helps a bit! (:

Y is directly related to x and y is 81 when x is 27 the constant of.variation is

suter [353]

Answer:

The constant of variation is 3

Step-by-step explanation:

Given.

$y=81$

$x=27$

And y is directly related to x

$y$ ∝ $x$

Here k is constant of variation

$y=kx$

$k=\frac{y}{x}$ --------------(1)

Put the $y$ and $x$ value in equation 1.

$k=\frac{81}{27}$

$k=3$

So, the constant of variation is 3.
