There are 540 degrees total in the interior angles of a regular pentagon.
Just so you know, the total degrees of interior angles goes up by 180 degrees.
A triangle is 180 degrees, a quadrilateral 360, and a pentagon 540.
Answer:
Step-by-step explanation:
I have attached the explanation above. hopefully this will help
Each month the new total you be
initial amount * 1.024
Repeating the process for a year (=12 months) you get
initial amount * 1.024^12
Being initial amount = $100
100*1.024^12 = $132.92
After 1 year you will have $132.92
Answer: b = 69
The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.
A triangle = 180
We know one angle is 42 and the other two angles are the same.
Subtract 42 from 180
180 - 42 = 138
Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2
138 divided by 2 = 69
So b = 69
