114/645 gives you the percentage of difference
Answer:
B,∠BAC=40°
Step-by-step explanation:
diameter makes 90° on the circumference.
∠CBA=90°
∠ACB+∠CBA+∠BAC=180°
50+90+∠BAC=180
∠BAC=180-140=40°

Multiply the fractions
Simplify the arithmetic:
1) A. since, if you put the numbers into the equation (one at a time) the equation = 0 each time, which is true.
2) I think I've been taught to complete the square slightly differently
x^2 - 18x - 17 = 0
(x-9)^2 - 81 -17 = 0
(x-9)^2 - 98 = 0
I hope you can get something from that
