<u>Statement | Reason </u>

1. m∠A + m∠B + m∠C = 180° | 1. Angles in a triangle sum to 180°

2. 28° + x - 4° + 2x = 180° | 2. Substitution

3. x=(180° - 24°)/3= 156°/3°= 52° | 3. Algebra

Sin θ = 12/37. Find tan θ.

ivann1987 [24]

Answer:

Step-by-step explanation:

Use SOHCAHTOA.

sinθ = $\frac{opposite}{hypotenuse}$

Opposite side length= 12

Hypotenuse length = 37

Find the adjacent side length (b) using the Pythagorean theorem.

$12^2 + b^2 = 37^2$

b = 35

tanθ = $\frac{opposite}{adjacent}$ = 12/35

Choice B is the correct answer.
