Answer:
Denote the O, A, B, C, D as shown in attached image:
O is center of circle.
OA = OC = OD = radius of circle
=> triangle OAD is isosceles
=> BA = BD = 12.8
Applying Pythagorean theorem:
OB = sqrt(OA^2 - BA^2) = sqrt(15.1^2 - 12.8^2) = 8.0
=> x = OC - OB = 15.1 - 8.0 = 7.1
Hope this helps!

Answer:
x = 0 , 1
Step-by-step explanation:
x² = x
x² - x = 0
x ( x-1 ) = 0
x=0 and x=1
the perimeter is 18.7 units
Answer:
i think 8
Step-by-step explanation:
The number of the students in the school that have had algebra is 203
<h3>How to determine the number of students?</h3>
The given parameters in the question are
- Proportion of students taking algebra, p = 70%
- Number of students in the school, n = 290
The number of students that had algebra in the school is calculated as:
Algebra = Proportion of students taking algebra * Number of students in the school
The above equation can be represented as:
Algebra = np
Substitute values for n and p in the above equation
So, we have
Algebra = 290 * 70%
Express 70% as decimal i.e. 0.70
So, we have
Algebra = 290 * 0.70
Evaluate the product i.e. multiply 290 and 0.70
So, we have
Algebra = 203
Hence, the number of the students in the school that have had algebra is 203
