If the sides 50m and 130m of the triangular field meet at angle of 72°, then find the area in which wheat is cultivated shaded portion.

Triangle :-

Solve for area :

$\boxed{ \bold{A≈3090.93m²}}$

$\small{ \sf{a \: Side = 50 \: m }}$

$\small{ \sf{ \: b \: Base = 130 \: m }}$

$\small { \sf{</p><p>γ \: Gamma = 72</p><p>{ \degree}}}$

Solution :-

$\small { \sf{A= \frac{absinγ}{2} </p><p>}}$

$\small{ \sf{ \: \: \: \: \: \frac{=50·130·sin(72°)</p><p>}{2} }}$

$\small{ \bold{ \boxed{≈3090.93368m²}}}$
