Answer:

Step-by-step explanation:
Answer:
Sine Formula or Sine Rule :
BC / sinA = AC / sinB
60 / sinA = 84.95 / sin(115°)
60 / sinA = 84.95 / 0.91
60 / sinA = 93.7
sinA = 60 / 93.7
sinA = 0.64
A = arc(sin0.64)
A = 39°48'30"
A ≈ 40°
Hence, the value of angle BAC is <u>40°</u>
- <u>40°</u> is the right answer.
Answer:
√3
Step-by-step explanation:
The given expression to be simplified is

but


Since √12=2√3,this implies that,

Therefore,



The simplified form of ,
is √3
Answer:
3.56 cm
Step-by-step explanation:
<em>Cube</em> is a 3D closed structure in which each adjacent side is perpendicular to each other and every side is equal to each other.
Let the side of cube be
cm.
Please refer to attached image of cube for a clear look and feel of a cube with each side = a units.
Then, volume of cube is given by the formula:

Here, we are given that:

![\Rightarrow a^3 = 45\ cm^3\\\Rightarrow a =\sqrt[3] {45}\\\Rightarrow a ={45}^\frac{1}{3}\\\Rightarrow a = 3.56\ cm](https://tex.z-dn.net/?f=%5CRightarrow%20a%5E3%20%3D%2045%5C%20cm%5E3%5C%5C%5CRightarrow%20a%20%3D%5Csqrt%5B3%5D%20%7B45%7D%5C%5C%5CRightarrow%20a%20%3D%7B45%7D%5E%5Cfrac%7B1%7D%7B3%7D%5C%5C%5CRightarrow%20a%20%3D%203.56%5C%20cm)
So, the answer is, Side of each petit four is,
.
