Answer:
The Required area of Δ
is
.
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
,
and
°
To find : The area of Δ
.
So, from the question
Area of triangle when two sides and one angle (between two known sides) are given
, where
is the given angle.
Substituting the given values in above to find area of Δ
we get,
![Ar(\triangle XYZ) = \frac{5\times6\times Sin\angle40}{2}](https://tex.z-dn.net/?f=Ar%28%5Ctriangle%20XYZ%29%20%3D%20%5Cfrac%7B5%5Ctimes6%5Ctimes%20Sin%5Cangle40%7D%7B2%7D)
![= 15\times0.642788](https://tex.z-dn.net/?f=%3D%2015%5Ctimes0.642788)
![= 9.6 \ cm^{2}](https://tex.z-dn.net/?f=%3D%209.6%20%5C%20cm%5E%7B2%7D)
Therefore, The Required area of Δ
is
.
