Answer:
144 = each interior angle
Step-by-step explanation:
The sum of the interior angles of a regular polygon is
(n – 2)180
If it is regular with n sides, divide by n to find each interior angle
(n – 2)180
------------------- = each interior angle
n
We know that there are 10 sides so n = 10
(10 – 2)180
------------------- = each interior angle
10
(8)180
------------------- = each interior angle
10
144 = each interior angle
The change would just be a subtraction of money worth $55 to Emily's total savings. As long as you know the value of Emily's savings, you can determine the savings balance or the change. They are just the same thing.
Answer:
x = -5/3
Step-by-step explanation:
Combine like terms: 2x + 3x = 5x - 1 (on the left) -6 + 2x (on the right) (5x - 1 = -6 + 2x)
Get X on one side: Isolate +2x by subtracting 2x on both sides (5x - 2x = 3x) (3x - 1 = -6) Isolate -1 by subtracting 1 on both sides (3x = -5) Isolate 3x by dividing 3 on both sides.
I hope I explained it correctly
Answer:
The scale factor of the smaller rectangle to the larger rectangle is 3/2
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem
To find out the scale factor of the smaller rectangle to the larger rectangle. set up a proportion
----> ratio of corresponding heights
or
----> ratio of corresponding bases
therefore
The scale factor of the smaller rectangle to the larger rectangle is 3/2
