If you flip the 30-60-90 triangles so they look similar, and find the difference between the length of 60, and the length of 40.

40÷60 =.6666 etc

You can prove this by plugging in
60 •.66666 = 39.9999 or about 40.

The triangle I started with had a length of 60, so just used the tangent of 60° to find the adjacent.
Since we know the relationship of the triangles,
Multiply your answer, 103.923 •.666666
Which equals 69.2819
69.2819 is the length of the 40 triangle.

Add them together, and you get 173.2049.

Or 173.20 m

Drag each figure to show if it is similar to the figure shown or why it is not similar
natita [175]

Answer:

In the given shapes above, we can see that all shapes have four sides.

Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.

First two shapes are Rectangles.

Third is a parallelogram.

Fourth and fifth shapes are Rectangles again.

Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)

Below shown shape has only three sides in it.

It is called a triangle when a shape has three sided close figure.

So, we could drag : Not similar - Different Type of shape.

What makes b in the equation true 3/8 X 8/b
Gala2k [10]

\frac{3}{8} *  \frac{8}{b} =  \frac{3}{1} *  \frac{1}{b}  (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1

HELP ME NOW ASAP PLEASE
sergejj [24]

Answer:

D. There are points on the graph with the same x-coordinate but different y-coordinate.

Step-by-step explanation:

A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.

Hence, correct answer is D.
