-10 -10y = 10
+10 +10
-10y = 20
20/-10 = -2
Y = -2
Density = mass / volume
Mass = 25.69g and Volume = 10 mL
D = 25.69g / 10mL
Density = 2.569 g/mL

Answer:
b/h
Step-by-step explanation:
remember SOH CAH TOA. Sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. So in this case use CAH for cos L. Adjacent to L is b, and the hypotenuse is h. Therefore the answer is b/h.
