Answer 1

Answer/Step-by-step explanation:

1. Sin A = opp/hyp

Opp = 3

Hyp = 5

$sin(A) = \frac{3}{5}$ (substitution)

$sin(A) = 0.6$

2. Sin B = opp/hyp

Opp = 4

Hyp = 5

$sin(B) = \frac{4}{5}$ (substitution)

$sin(B) = 0.8$

3. Cos Q = adjacent/hypotenuse

Adjacent = 12

Hypotenuse = 13

$cos(Q) = \frac{12}{13}$ (substitution)

$cos(Q) = 0.9231$ (4 decimal places)

4. Cos S = adjacent/hypotenuse

Adjacent = 5

Hypotenuse = 13

$cos(S) = \frac{5}{13}$ (substitution)

$cos(S) = 0.3846$ (4 decimal places)
