Hello!
You first have to find the scale factor between the triangles
To do this you divide the new side length by the old one
9 / 6 = 1.5
They multiplied the smaller triangle by 1.5 to get the bigger one
Do this to find the missing length
8 * 1.5 = 12
The answer is 12
Hope this helps!
Answer:
$27.75
Step-by-step explanation:
Multiply $2.25 by 11 to get the answer
It is decreasing percentage at 40%
Answer:
As the number of sides increases, the measures of the angles increase
see the explanation
Step-by-step explanation:
we know that
The measure of the interior angle in a regular polygon is equal to
where
n is the number of sides of the regular polygon
x is the measure of the interior angle in a regular polygon
we have that
<u><em>Examples</em></u>
<em>A triangle</em>
n=3 sides
<em>A square</em>
n=4 sides
<em>A pentagon</em>
n=5 sides
<em>A hexagon</em>
n=6 sides
so
n ----> 3,4,5,6...
x ----> 60°,90°,108°,120°,...
As the number of sides increases, the measures of the angles increase
