Well if
1 cup makes 1.5 cups that means its 1.5*cups
so
1 cup= 1.5
2 cups=3
3 cups= 4.5
Hope this helps
Answer:
a) side length z = 19.965 ≅ 20m
b) angle 'd' = 53.13°
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that ∠HIG is a right angle triangle
Given∠I = 53°
By using the sine function
![sin53 = \frac{opposite side}{hypotenuse} =\frac{z}{25}](https://tex.z-dn.net/?f=sin53%20%3D%20%5Cfrac%7Bopposite%20side%7D%7Bhypotenuse%7D%20%3D%5Cfrac%7Bz%7D%7B25%7D)
z = 25 × sin53° = 25×0.798635
z = 19.965 ≅20 m
<u><em>Step(ii):-</em></u>
![sind = \frac{8}{10} = \frac{4}{5}](https://tex.z-dn.net/?f=sind%20%3D%20%5Cfrac%7B8%7D%7B10%7D%20%3D%20%5Cfrac%7B4%7D%7B5%7D)
⇒ ![d = sin^{-1} (\frac{4}{5} )](https://tex.z-dn.net/?f=d%20%3D%20sin%5E%7B-1%7D%20%28%5Cfrac%7B4%7D%7B5%7D%20%29)
<em>⇒ d = 53.13°</em>
<u><em>Final answer:-</em></u>
a) side length z = 19.965 ≅ 20m
b) angle 'd' = 53.13°
We have two sides and one angle opposite to one of the known sides.
Begin with applying the Law of Sines to find angle A:
![\frac{sin A }{a}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bsin%20A%20%7D%7Ba%7D%20)
= <span>
![\frac{sin C }{c}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bsin%20C%20%7D%7Bc%7D%20)
Then, solve for sin A:
</span>sin A =
![\frac{a sinC}{c}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20sinC%7D%7Bc%7D%20)
Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17
We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
First you have to use the formula which is r to the second times height times pi
You would do 4 times 2 equals 8 then multiply 8 times 10 equals 80 then multiply that answer times 3.14 then your answer is 251.2
