Step-by-step explanation:

Answer 2

CosA = 5/13 and TanA = 12/5.

Step-by-step explanation:

13 SinA = 12.

SinA = Opposite/Hypotenuse.

SinA = 13/12.

By using Pythagoras theorem

→ AC² = AB² + BC².

AB = 12 , BC = ? , AC = 13.

→ 13² = 12² + BC².

→ 169 = 144 + BC².

→ 169 - 144 = BC².

→ 25 = BC².

→ √25 = BC.

→ 5 = BC (OR) BC = 5.

CosA = Adjacent/Hypotenuse.

CosA = 5/13.

TanA = Opposite/Adjacent.

TanA = 12/5.
