The angles of a quadrilateral measures 80 degrees 100 degrees 100 degrees in this order. What kind of quadrilateral has this sha

bija089 [108]

A parallelogram

Because...
-opposite angles are congruent
-four sides
-angles must equal 360
100 + 100 +80 + y = 360

280 + y = 360

y = 80
-the angle we don't know is 80 degrees

r-ruslan [8.4K]

Answer:

The equation has an Inifinite amount of solutions

Step-by-step explanation:

2 ( 3g + 2 ) = 1/2 ( 12g + 8 )

First use the distributive property of multiplication -

6g + 4 = 6g + 4

6g cancels out from both sides of the equation -

4 = 4

When both sides of an equation are the same there is an infinite amount of solutions.

Hope this helped! :)

Write the standard form of the equation of the circle described below.

Luden [163]

Equation of circle is $x^2+(y+2)^2=26$

Step-by-step explanation:

The standard form of the equation of circle is:

$(x-h)^2+(y-k)^2=r^2$

where (h,k) is the center of the circle and r is the radius of circle.

We need to find the radius of circle r by using distance formula:

$r=d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\\r=d=\sqrt{(-5-0)^2+(-1-(-2))^2}\\r=d=\sqrt{(-5)^2+(1)^2}\\r=d=\sqrt{25+1}\\r=d=\sqrt{26}$

r=√26

and r^2= 26

Putting values of r^2=26 and value of center (h,k)=(0,-2)

the equation of Circle is:

$(x-h)^2+(y-k)^2=r^2\\(x-0)^2+(y-(-2)^2=26\\x^2+(y+2)^2=26$
