Which equation can be used to solve forB?

Answer:tan 30 = 5/b
Step-by-step explanation:
From the diagram line BC is opposite to the angle 30 and line AC is adjacent to that same angle
From trigonometric ratios
Tan 30 = opposite /adjacent
Answer:
The correct answer is first option
Step-by-step explanation:
Points to remember
Trigonometric ratio
Tan θ = Opposite side/Adjacent side
From the figure we can see that a right angled triangle ABC
BC = 5 cm, <A = 30° and <C = 90°
To find the correct equation
We have,
Tan θ = Opposite side/Adjacent side
Tan 30 =BC/AC
Tan 30 = 5/b
The correct answer is first option.
