Answer:
A: Opposite sides of a parallelogram are congruent
Step-by-step explanation:
The only diagonal involved is BD, so none of the statements regrading diagonals has been proven. The only thing proven is ...
AB ≅ CD . . . . opposite sides are congruent
AD ≅ CB . . . . opposite sides are congruent
This is an angle of elevation problem. So, we use the tangent ratio.
tan84=x/150
this then becomes
x=150(tan84)
which simplifies to
150∗(tan84)=1427
Since she only begins to observe the building 5 feet higher than where it starts, we add 5+1427, so your final answer is 1432 feet tall!
Answer:
the time is 1.57 sec and the distance is 49.32mm
Step-by-step explanation:
Given that,
The angle is 180°
Angular velocity is 2rev/sec
The radius is 10mm
we are to find the time and distance traveled at that time
The formula is
θ = at
where t is the time,
a is the angular velocity
θ is angle in radian
so,
θ = 180° × π/180°
θ = π
= 3.14
Hence ,
θ = at
3.14 = 2t
t = 1.57sec
let the distance be xmm
Therefore , the time is 1.57 sec and the distance is 49.32mm
Answer:
285
Step-by-step explanation:
1175 divided by 412 = 2.85194174757
that would be around 2.85
