Step-by-step explanation:
Answer:
B
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:
x < 3
Step-by-step explanation:
Solve it like a normal equation
Isolate the variable along with its constant
9x - 6 + 6< 21 + 6
9x < 27
Isolate the variable its self
9x/9 < 27/9
x < 3
