Answer 1

Trigonometry
Three sides measurment
measurement of three sides is trigonomentry


following ratios are dysired as-
$sin\theta =\frac{p}{h}\to cosec\theta =\frac{h}{p}=\frac{1}{sin\theta }cos\theta =\frac{b}{h}\to sec\theta =\frac{h}{b}=\frac{1}{cos\theta }\left(\frac{sin\theta }{cos\theta }\right)=tan\theta =\frac{p}{b}\to cot\theta =\frac{b}{p}=\frac{1}{tan\theta }=\frac{cos\theta }{sin\theta }$
