Given,
The diagram of the circle and the central angles is hown in the question.
Required
The value of x.
Here, the angle formed by the chord (2x+1) is on the circle measure 25 degree. The angle formed by the chord x+3 on the center of the circle measure 50 degree.
The angle formed on the center of the circle is equal to the double of angle formed on the circle, then the measure of the chord is equal.
Therefore,
Hence, the value of x is 2.
Step-by-step explanation:

Answer:
1.) D
2.) B
3.)
a.) 7x-34
b.) x (division symbol) 45 + 6
4.)
a.) x decreased by 216
b.) the quotient of 15 and x
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
Here, a = -9, b = 2 and c =3
Put the values,
So, the solution are -0.47 and 0.69.
