This is an interesting question. I chose to tackle it using the Law of Cosines.
AC² = AB² + BC² - 2·AB·BC·cos(B)
AM² = AB² + MB² - 2·AB·MB·cos(B)
Subtracting twice the second equation from the first, we have
AC² - 2·AM² = -AB² + BC² - 2·MB²
We know that MB = BC/2. When we substitute the given information, we have
8² - 2·3² = -4² + BC² - BC²/2
124 = BC² . . . . . . . . . . . . . . . . . . add 16, multiply by 2
2√31 = BC ≈ 11.1355
Answer:
Round to the nearest thousand.
5,568
= 5,000
Answer: more than 1/2
Step-by-step explanation: 1/2 equals 2/4 so 3/4 is more.
0.825200
(correct me if I’m wrong)
Answer:
y = -75
Step-by-step explanation:
Simplify both sides of equation
1/5y = -15
multiply both side by 5
1/5y * 5 = -15 * 5
y = -75
