Pagal sinusų teoremą
2sin(30)=xsin(45)\frac{2}{sin(30)} = \frac{x}{sin(45)}sin(30)2=sin(45)x
x=2⋅sin(45)sin(30)x = \frac{2\cdot sin(45)}{sin(30)}x=sin(30)2⋅sin(45)
x=2⋅22⋅(12)x = \frac{2\cdot \sqrt {2}}{2\cdot (\frac{1}{2})}x=2⋅(21)2⋅2
x=212x = \frac{\sqrt {2}}{\frac{1}{2}}x=212
x=2⋅2x = 2\cdot \sqrt {2}x=2⋅2
Atsakymas: 2⋅22\cdot \sqrt {2}2⋅2
