Mga Hakbang ng Solution

Evaluate trigonometric functions in the problem

$$4 \cdot 0.25881904510252074 \cdot 2 \cdot 0.766044443118978 = 2 \cdot 0.17364817766693033$$

I-cancel out ang 2 sa parehong panig.

$$4\times 0.25881904510252074\times 0.766044443118978=0.17364817766693033$$

I-multiply ang 4 at 0.25881904510252074 para makuha ang 1.03527618041008296.

$$1.03527618041008296\times 0.766044443118978=0.17364817766693033$$

I-multiply ang 1.03527618041008296 at 0.766044443118978 para makuha ang 0.79306756509658460206982213041488.

$$0.79306756509658460206982213041488=0.17364817766693033$$

Ikumpara ang 0.79306756509658460206982213041488 at 0.17364817766693033.
