The measure of an angle is eighty-nine times the measure of a supplementary angle. What is the measure of each angle?

1 answer:

4 0

Supplementary angles add up to 180°.

$x+89x=180^\circ \\
90x=180^\circ \ \ \ |\div 90 \\
x=2^\circ \\ \\
89x=89 \times 2^\circ=178^\circ$

The measures of the angles are 2° and 178°.

The coordinates of the vertices of a regular polygon are given. Find the area of the polygon to the nearest tenth.

alexandr1967 [171]

Answer:

The area is equal to $8\ units^{2}$

Step-by-step explanation:

we have

A(0, 0), B(2, -2), C(0, -4), D(-2, -2)

Plot the figure

The figure is a square (remember that a regular polygon has equal sides and equal internal angles)

see the attached figure

The area of the square is

$A=AB^{2}$

Find the distance AB

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$AB=\sqrt{(-2-0)^{2}+(2-0)^{2}}$

$AB=\sqrt{(-2)^{2}+(2)^{2}}$

$AB=\sqrt{8}$

$AB=2\sqrt{2}\ units$

Find the area of the square

$A=(2\sqrt{2})^{2}$

$A=8\ units^{2}$

Alenkinab [10]

Answer:

We are assuming the numbers 1 - 6 on the cubes?

If so,

Blue (3, 4, 5, or 6) is 4/6 or 2/3 chance

Green(1,3,5) is 3/6 or 1/2 chance

To get both the P is 2/3 times 1/2
