We use a conjecture that says that the perpendicular bisector of a chord in a circle passes through the center of the circle.
The distances of the two bisectors are the same so the chord lengths are the same.
b = half of 22.5 = 11.25
The answer to your question is 11.25.
3/2 is the correct answer for your problem
Answer: -2a + 16
Step-by-step explanation:
You must do the distributive property. Since "a-8" is in the parenthesis and -2 is outside the parenthesis, you must multiply -2 by (a-8). -2 multiplied by a will equal 2a since you don't know what variable a equals. Next, you multiply -2 and -8 which would equal positive 16. The reason why it is positive is because 2 negative numbers multiplied or divided would equal a positive number. Thus, the answer is -2a + 16.
