Given:
A figure of a circle.
To find:
The value of x.
Solution:
Central angle theorem: According to this theorem, the central angle on an arc is twice of the subtended angle on that arc.
Using the central angle theorem, we get


Therefore, the value of x is 70 degrees.
So hmm notice the first picture, that's the "inscribed angle theorem", as you'd know
now, notice angle 2 in yours on the second picture
Answer:
The required inequality is: 
Step-by-step explanation:
Consider the provided information.
Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.
Let the number of hours Gurnaz work is represented by x.
Gurnaz will need to work for at least six hours to save enough money,
That means he can work 6 or more than 6 hours,

He must work fewer than 16 hours this week. That means the value of x should be less than 16.

Thus, the required inequality is: 
Now draw the graph of the inequality.
Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.
The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.
8x^2 -3 = 2
add 3 to each side
8x^2 = 5
divide by 8
x^2 =5/8
take the square root of each side
x = +- sqrt (5/8)
