Answer:
h = 1.403733341286
Step-by-step explanation:
17.
the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then

Then

Then

18.
For l = 6 and θ = 40 :

= 6-6cos(40)
= 1.403733341286
Add the ratio together: 2 + 5 = 7
Divide this by the total number of plants;
70/7 = 10
Now times the ration by this number:
2:5 becomes 20:50 (times by 10)
This tells us we have 20 tulips as 50 daisies
Answer:
- The length of VW = 36 units.
Step-by-step explanation:
We know that a rhombus is a quadrilateral with four sides. All four sides have the same length.
From the diagram, it is clear that
As all the four sides of the rhombus have equal length.
So we can observe


Add 12 to both sides



Divide both sides by 2


so
The length of VW= 6m-12
= 6(8)-12 ∵ 
= 48-12
= 36
Thereofore, the length of VW = 36 units.
Since, the angle between the machine and angle of press is
as shown in the attached image.
Therefore, the actual weight lifted by the power lifter is given by
where 'w' stands for the weight being lifted and
is the angle of press.
Now,
actual weight lifted by the power lifter = 
=
pounds.
40^2 - 32^2=576
square root of 576 will be 24 so 24 is y
