Step-by-step explanation:
First calculate BD using sine ratio in Δ BCD and the exact value
sin60° = , thus
sin60° = =
=
=
( cross- multiply )
2BD = 12 ( divide both sides by 2 )
BD = 6

Calculate AD using the tangent ratio in Δ ABD and the exact value
tan30° = , thus
tan30° = =
=
=
( cross- multiply )
AD = 6
( divide both sides by
)
AD = 6 → B
Answer:
Step-by-step explanation:
The given equation is:
To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have .
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5
