Question

Cos theta=8/17. Find tan thetaA. 15/8B. 15/17C. 17/15D. 8/15​

Answer 1

Answer:

A) $\frac{15}{8}$

Step-by-step explanation:

remember Soh Cah Toa!!

$sin=\frac{opposite}{hypotenuse}\\ cos=\frac{adjacent}{hypotenuse} \\tan=\frac{opposite}{adjacent} \\\\cos=\frac{8}{17}\\\\a^2+b^2=c^2\\8^2+b^2=17^2\\64+b^2=289\\b^2=225\\\sqrt{b^2} =\sqrt{225}\\b=15=opposite\\\\tan=\frac{15}{8}$
