Answer:
![x=\sqrt{40}, y=\sqrt{104}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B40%7D%2C%20y%3D%5Csqrt%7B104%7D)
Step-by-step explanation:
Note the triangle formed by x, y, and 8 is similar to the largest triangle
so x : c = 8 : y = y : 13, where c is the rightmost vertical length, c² = x² + 5²
From 8 : y = y : 13, we get
y² = 13*8 = 104, so
![y=\sqrt{104}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B104%7D)
From x : c = 8 : y, we have xy = 8c
x²y² = 64c²
104x² = 64(25 + x²)
104x² = 1600 + 64x²
40x² = 1600
x² = 40
![x=\sqrt{40}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B40%7D)

Answer:
sin(-π/6) = -1/2
Step-by-step explanation:
sin(π/6) = 1/2 is a value we have memorized.
sin(-π/6) = -sin(π/6) = -1/2
