The angles below AB will add to 180°.
.. x +2x +x +3x = 180°
.. 7x = 180°
.. x = 180°/7 ≈ 25.71°

Vertical angles AOC and BOD are equal, so
.. 2y = 3x
.. y = (3/2)*x = (3/2)*25.71° = 38.6° . . . . . . . . corresponding to selection D.

___
There is an "x" missing next to segment OC. "2" should be "2x".

Notice that 2y and 3x are vertical angles, which means they are equal.
2y=3x

the four angles below the line AB make a sum of 180
 3x+x+2x+x=180
7x=180
x=180/7

2y=3x=3*180/7=540/7
y=270/7≈38.6
d is the answer.

Find the product. (y3)^2 · y^7
Sedbober [7]
Hey there! :D

When powers are outside the parenthesis, you multiply them. When they are not, you add them.

(y^3)^2 * y^7

3*2= 6

y^6*y^7

Add the powers. 

y^13= the simplest form

I hope this helps!

Qaudriladrial ABCD had cordinates A (3, 5) B(5, 2) C(8, 4) D(6, 7) qaudriladrial ABCD is a what?
Lorico [155]

The quadrilateral is a square

<h3>What are quadrilaterals?</h3>

Quadrilaterals are polygons, that have four sides and four corners

The coordinates are given as:

  • A = (3, 5)
  • B = (5, 2)
  • C = (8, 4)
  • D = (6, 7)

Start by calculating the adjacent side lengths using:

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

So, we have:

AB = \sqrt{(3- 5)^2 + (5- 2)^2}

AB = \sqrt{13}

BC = \sqrt{(8- 5)^2 + (4- 2)^2}

BC = \sqrt{13}

The side lengths are equal.

Hence, the quadrilateral is a square
