Step1: 삼각함수 정의 사용
\(\tan x^{\circ}=\frac{16}{10}\)
Step2: \(x\) 값 계산
\(x = \arctan(\frac{16}{10})\)
\(x\approx58^{\circ}\)
Step1: 코사인 함수 정의 사용
\(\cos17^{\circ}=\frac{x}{9.7}\)
Step2: \(x\) 값 계산
\(x = 9.7\times\cos17^{\circ}\)
\(x\approx9.2657\)
Step1: 탄젠트 함수 정의 사용
\(\tan63^{\circ}=\frac{x}{50}\)
Step2: \(x\) 값 계산
\(x = 50\times\tan63^{\circ}\)
\(x\approx98.4808\)
