13.9
it’s a special triangle and that side would be 8√3 which is 13.9
Note that 2x-y=8 can be solved for y: y=2x-8. This is identical to the first equation. The graph of one is exactly the same as the graph of the other. Thus, the two equations are dependent.
Answer:
32 years old
Step-by-step explanation:
Reverse what the teacher said. Half 120 to get 60. Subtract 28 from 60. The teacher is 32.
Answer:
X= -4
Step-by-step explanation:
^ you have to isolate the radical than raise each side to the power of its index which gets you
x= -4
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
