All sides are congruent in quadrilateral ABCD below.

emmainna [20.7K]

Answer:

rhombus; Measure of angle B = 70 degrees

Step-by-step explanation:

The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.

110 + B = 180

B = 180 - 110

B = 70

It is a rhombus because all sides are equal.

20. Two collinear rays that do not intersect? How would I draw this?

eimsori [14]

Answer:

Two collinear rays are parallel to each other.

Step-by-step explanation:

Two collinear rays parallel to each other, and they are on the same plane. Thus they do not meet even when extended till infinity.

An example of collinear rays is when you draw two parallel rays on a plain paper placed on an horizontal surface.

Your drawing should look like what is attached to this answer.

For a right triangle that has legs a and b and hypotenuse c, find the lengt h of the side not given here a-1 c= square root of 3

denis-greek [22]

Use the Pythagorean theorem:
$c^2=a^2+b^2$
We have:
$a=1;\ c=\sqrt3$
Substitute:
$1^2+b^2=(\sqrt3)^2\\\\1+b^2=3\ \ \ |-1\\\\b^2=2\to b=\sqrt2$
<span>We calculate the area of the triangle by two methods:</span>
$A_\Delta=\dfrac{ab}{2}\ and\ A_\Delta=\dfrac{ch}{2}$

$\dfrac{h\sqrt3}{2}=\dfrac{1\sqrt2}{2}\ \ \ \ |\cdot2\\\\h\sqrt3=\sqrt2\ \ \ |\cdot\sqrt3\\\\3h=\sqrt6\ \ \ |:3\\\\h=\dfrac{\sqrt6}{3}$
