hello
to solve this problem, let's open the bracket and simplify
It seems that you have missed to attach the necessary details for us to answer this given question, so I had to look for it. Anyway, here is the answer. Given that phylogenies are based on shared derived characteristics, the trait that is useful <span>in generating a phylogeny of species w, x, y, and z is TRAIT 2. Hope this helps.</span>
Answer:
(0, 2)
Step-by-step explanation:
The x-coordinate is 0 because the y-intercept is where the line crosses the x-axis. The y-intercept is the number on its own in the equation (in the form y = mx + c)
Hope this helps!
Answer:
m∠B = 111º
Step-by-step explanation:
use law of cosines
c² = a² + b² - 2ab*cosC
---------------------------------
15² = 7² + 11² - 2(7)(11)cosB
225 = 49 + 121 - 154cosB
225 = 170 - 154cosB
Subtract 170 form both sides
55 = -154cosB
Divide both sides by -154
-0.3571428571 = cosB
m∠B = arccos -0.3571428571
use calculator
m∠B = 110.924832425009406
Rounded
m∠B = 111º
