Answer:
m∠I = 58.4°
Step-by-step explanation:
cos = adjacent side/hypotenuse
It is always helpful to have a picture. In your case KI is adjacent to ∠I and IJ is the hypotenuse.
So cos I = KI/IJ = 4.5/8.6
arccos (4.5/8.6) = m∠I
m∠I = 58.4°
It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems. OK?
Answer:
C7,3=7!( 3!)( 7−3)!= 7! I think tell me if I'm wrong?

Step-by-step explanation:
Answer:
[H^+] = Antilog[-6]
Step-by-step explanation:
Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.
pH=−log[logH^+]
-pH = log[H^+]
[H^+] = Antilog[-pH]
Since pH =6
The equation is;
[H^+] = Antilog[-6]
