Step-by-step explanation:
(-5)+7=2
2-18= -16
-16+4= -12
Answer:

Step-by-step explanation:
0.6 = six tenths
percent = per 100
so 0.6 = 60%
Memorize Soh Cah Toa, which means:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite & adjacent are determined based on the angle being referenced.
hypotenuse is ALWAYS opposite of the 90 degree angle.
sin Y = 12/13
cos Y = 5/13
tan Y = 12/5
