when the altitude is drawn from the vertex of the right angle of a right triangle to its hypotenuse, the altitude equals the product of the two segments of the hypotenuse.
(w+9)²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)
use the same method, z=√(9*11)=3√11
next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55

Om I really hate my math teacher to go he talks to fast and don’t makes sense like lol
Answer from: Quest
hope it you
step-by-step explanation:
sin(7pi/6 - pi/3)
= sin(7pi/6 - 2pi/6)
= sin(5pi/6)
= sin(pi - pi/6)
= sin(pi/6)
= 1/2
sin 7pi/6 - sin pi/3
= sin (pi + pi/6) - sin pi/3
= -sin pi/6 - sin pi/3
= -1/2 - sqrt(3)/2
= -(1+sqrt(3))2
