Answer:
in steps
Step-by-step explanation:
upper: a₁ = 50
t = a₁ - s
lower: a₁ = 1
z = a₁ + 5 n
Sin A=Cos (90º-A)
Then:
sin 30º=cos (90º-30º)=Cos 60º=1/2
Answer: cos 60º=1/2
We cant answer the question without the diagram.
Alright here we go...
<u>(-18) + (-15) - 23</u>
-33 - 23
= -56
<u>15-18+23</u>
-3 + 23
= 20
so I don't know how you want me to compare it but,
(-18) + (-15) - 23 < 15-18+23
