인기 있는 삼각법 >

(368.02)/(sin(66-x))=(290)/(sin(38))

해법

\frac{368.02}{sin ( 6 6 ^{\circ} - x )} = \frac{290}{sin ( 3 8 ^{\circ} )}

해법

x = - 36 0^{\circ} n + 6 6^{\circ} - 0.89673 \dots, x = - 18 0^{\circ} - 36 0^{\circ} n + 6 6^{\circ} + 0.89673 \dots

+1

라디안

x = \frac{11 π}{30} - 0.89673 \dots - 2 πn, x = - π + \frac{11 π}{30} + 0.89673 \dots - 2 πn

솔루션 단계

\frac{368.02}{sin ( 6 6 ^{\circ} - x )} = \frac{290}{sin ( 3 8 ^{\circ} )}

교차 곱셈

\frac{368.02}{sin ( 6 6 ^{\circ} - x )} = \frac{290}{sin ( 3 8 ^{\circ} )}

분수 교차 곱셈 적용: 다음과 같습니다

\frac{a}{b} = \frac{c}{d}

그리고나서

a \cdot d = b \cdot c

368.02 sin (3 8^{\circ}) = sin (6 6^{\circ} - x) \cdot 290

368.02 sin (3 8^{\circ}) = sin (6 6^{\circ} - x) \cdot 290

측면 전환

sin (6 6^{\circ} - x) \cdot 290 = 368.02 sin (3 8^{\circ})

양쪽을 다음으로 나눕니다

290

sin (6 6^{\circ} - x) \cdot 290 = 368.02 sin (3 8^{\circ})

양쪽을 다음으로 나눕니다

290

\frac{sin ( 6 6 ^{\circ} - x ) \cdot 290}{290} = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

단순화

sin (6 6^{\circ} - x) = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

sin (6 6^{\circ} - x) = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

솔루션 확인

정의되지 않은 (특이점) 점 찾기:

sin (6 6^{\circ} - x) = 0

의 분모를 취하라

\frac{368.02}{sin ( 6 6 ^{\circ} - x )}

그리고 0과 비교한다

sin (6 6^{\circ} - x) = 0

다음 지점은 정의되지 않았습니다

sin (6 6^{\circ} - x) = 0

정의되지 않은 점을 솔루션과 결합:

sin (6 6^{\circ} - x) = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

트리거 역속성 적용

sin (6 6^{\circ} - x) = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

일반 솔루션

sin (6 6^{\circ} - x) = \frac{368.02 sin ( 3 8 ^{\circ} )}{290}

sin (x) = a \Rightarrow x = arcsin (a) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (a) + 36 0^{\circ} n

6 6^{\circ} - x = arcsin (\frac{368.02 sin ( 3 8 ^{\circ} )}{290}) + 36 0^{\circ} n, 6 6^{\circ} - x = 18 0^{\circ} - arcsin (\frac{368.02 sin ( 3 8 ^{\circ} )}{290}) + 36 0^{\circ} n

6 6^{\circ} - x = arcsin (\frac{368.02 sin ( 3 8 ^{\circ} )}{290}) + 36 0^{\circ} n

해결 :

x = - 36 0^{\circ} n + 6 6^{\circ} - arcsin (\frac{368.02 sin ( 3 8 ^{\circ} )}{290})
