Answer 1

Answer:

The answer to your question is below

Step-by-step explanation:

sin Ф = Opposite side / hypotenuse

cosФ = Adjacent side / hypotenuse

tan Ф = Opposite side / Adjacent side

For this right triangle

Opposite side = 5

Adjacent side = 12

Hypotenuse = 13

Then,

sin Ф = 5/13

cos Ф = 12/13

tan Ф = 5/12

Answer 2

Answer:

SinФ = opp / Hyp = 5/13

CosФ = Adj/Hyp = 12/13

TanФ = Opp/ Adj = 5/12

Step-by-step explanation:

The values for the Trigonometry ratios are easily memorised with this mnemonics.

SohCahToa.

Soh (sinФ) = Opposite / Hypotenuse

Cah (cosФ) = Adjacent / Hypotenuse

Toa (TanФ) = Opposite / Adjacent

From the figure given:

Opposite = 5

Adjacent = 12

Hypotenuse = 13

Now, let's solve it completely:

SinФ = opp / Hyp = 5/13

CosФ = Adj/Hyp = 12/13

TanФ = Opp/ Adj = 5/12

Always try to remember your SohCahToa.
