خطوات الحلّ

\frac{( 2.68 \cdot 9.80665 )}{sin ( 7 5 ^{\circ} )}

= \frac{\frac{67}{25} \cdot \frac{196133}{20000}}{sin ( 7 5 ^{\circ} )}

Rewrite using trig identities:

sin (7 5^{\circ}) = \frac{6 + 2}{4}

sin (7 5^{\circ})

Rewrite using trig identities:

sin (4 5^{\circ}) cos (3 0^{\circ}) + cos (4 5^{\circ}) sin (3 0^{\circ})
