Answer:

AB is congruent is CD. (Last one)

Step-by-step explanation:

Hypotenuse leg is when the hypotenuse and ONE (you only need one, not two) leg of the triangle are congruent in a RIGHT triangle.

In the image, you already know that it is a right triangle and you know that the hypotenuse are congruent (Reflexive Prop) .You just need to know that the legs are congruent. So you choose which one has the legs congruent. The leg pairs that can be congruent are AD and CB or DC and AB. The only one that matches this is the last one

Using the digits 0-9, at most one time each, create five ordered pair that represent a linear

krok68 [10]

Answer:

(-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4)

Step-by-step explanation:

From the graph attached,

Ordered pairs which lie on the given line (-9, 0), (0, 3), (3, 4), (6, 5) and (9, 6).

Since all the points lie on the same line, rate of change of the linear function will be defined by the slope of the given line.

Slope of the line passing through (0, 3) and (3, 4) = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{4-3}{3-0}$

$m_1$ = $\frac{1}{3}$

Now we have to find the ordered pairs which represent a linear function having slope greater than $\frac{1}{3}$ .

So the points will be (-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4).

Slope of the linear function passing through (-9, 0) and (-8, 1)

$m_2$ = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{1-0}{-8+9}$

= 1

Here $m_2>m_1$

Is the golden ratio a coincidence or grand design

DENIUS [597]

The Golden number is one of the roots of x²-x-1=0 and x = (1+√5)/2= 1.618
It's just a mathematical constant you can come across in trigonometry, geometry, sequence like Fibonacci and others. You may find it in fractals also and in many shapes in the nature but not necessarily always true.

It might be a coincidence in some natural shapes, but definitely it is a recognized math contant useful in many math domains
