Answer:
Step-by-step explanation:
adjacent=5 ,hypotenuse13 opposite=?
hypotenuse^2=opposite^2+adjacent^2
13^2=opposite^2+5^2
169-25=opposite^2
=opposite
12=opposite
SinA=opposite/hypotenuse
12/13
therefore sinA =`12/13
.6+.03+.002 should be the answer
1.2 • 10^-1 = 0.12 g
6.0 • 10^-2 = 0.06 g
0.12 + 0.06 = 0.18
0.18 = 1.8 • 10^-1
Isn’t there any words or some thing
