Answer:
140°
Step-by-step explanation:
180°=(4x-20)+×
180° = 5x-20
200°=5x
x=40°
140°+40°=180°

The equation of a circle:
Step-by-step explanation:
The equation of a circle:
(where the center is known as and the radius, known as ).
-Since you already have the center and the radius, use them for the equation of a circle:
Center:
Radius:
After you have the equation of a circle, simplify the radius by the exponent :
So, you have found the equation of a circle.
Given:
Annual interest rate = r%
Growth factor : x = 1 + r
The below function gives the amount in the account after 4 years when the growth factor is x .
To find:
The total amount in the account if the interest rate for the account is 3% each year and initial amount.
Solution:
Rate of interest = 3% = 0.03
Growth factor : x = 1 + 0.03 = 1.03
We have,
Substitute x=1.03 in the given function, to find the total amount in the account if the interest rate for the account is 3% each year.
Therefore, the total amount in the account is 2431.31 if the interest rate for the account is 3% each year.
For initial amount the rate of interest is 0.
Growth factor : x = 1 + 0 = 1
Substitute x=0 in the given function to find the initial amount.
Therefore, 2250 was put into the account at the beginning.
Given:
The expression is
To find:
The factors of the given expression.
Solution:
We have,
First taking common, the given expression can be written as
Taking common from , we get
Therefore, the factors of the given expression are .
