Explanation:
Given
Triangle VWU
Required
Determine the Area of the Triangle
First, we'll solve for the third angle
Angles in a triangle when added equals 180; So
![36 + 24 + <V = 180](https://img.qammunity.org/2021/formulas/mathematics/high-school/zkexepqhkgprfwb71pmoags8wajfeifi0n.png)
![60 + <V = 180](https://img.qammunity.org/2021/formulas/mathematics/high-school/2tex7bphyajccond2xprdfk7bstbnf606h.png)
![<V = 180 - 60](https://img.qammunity.org/2021/formulas/mathematics/high-school/yjhywgc75h3o82fp6yfp9c18t3l56841w3.png)
![<V = 120](https://img.qammunity.org/2021/formulas/mathematics/high-school/pov9ks7o0yp1mzxedn6vepsl5fgrlti0yv.png)
Next is to determine the length of VW using Sine Law which goes thus
(Because 24 degrees is the angle opposite side VW)
Multiply both sides by Sin24
![SIn24 * (VW)/(Sin24) = (34)/(Sin36) * Sin24](https://img.qammunity.org/2021/formulas/mathematics/high-school/3pvpo4f01ptq74k6h5z3guo3eelnzglhlt.png)
![VW = (34)/(Sin36) * Sin24](https://img.qammunity.org/2021/formulas/mathematics/high-school/dn3c9d6qreu7jum7pafdmlfmzd2zm0da4q.png)
![VW = (34)/(0.5878) * 0.4067](https://img.qammunity.org/2021/formulas/mathematics/high-school/5m0h3imyvymsflev9fwciz1rn7chxmutai.png)
(Approximated)
At this stage, we have two known sides and two known angles;
The Area can be calculated as the 1/2 * the products of two sides * Sin of the angle between the two sides
Considering VW and VU
VW = 23.5 (Calculated);
VU = 34 (Given)
The angle between these two sides is 120 (Calculated);
Hence;
![Area = (1)/(2) * 23.5 * 34 * Sin120](https://img.qammunity.org/2021/formulas/mathematics/high-school/x4uhombth1cda0d16nstbqpjbw9irmcj16.png)
![Area = (1)/(2) * 23.5 * 34 * 0.8660](https://img.qammunity.org/2021/formulas/mathematics/high-school/5xcnhgbs87s5odkznlrutdzy69d1go1f94.png)
![Area = (1)/(2) * 691.934](https://img.qammunity.org/2021/formulas/mathematics/high-school/5pwi1ha6mnmrrk0cl5ip72m6lbd47u78k4.png)
![Area = 346.0 mm^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/bmbkbh0tikssslzmgw0u7ke52nypqp37ve.png)
Hence, the area of the triangle is
![346.0\ mm^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/rxyny4xj301in5rmq229la7uekdjkzafq9.png)
