Question

a right angle has an acute angle θ such that sinθ=5/8. find the exact value of tanθ

Answer 1

soh cah toa

Answer 2

\[\sin \theta = \frac{perpendicular}{hypotenuse}= \frac{5}{8}\]use pythagorus theorem & find base then \[\tan \theta = \frac{perpendicular}{base}= ??\]

Answer 3

\[h^2=p^2+b^2.\rightarrow Pythagorus \space theorem.\]
