“If sin = 3 5 sin= 5 3 and is an acute angle, find…
Given: sin theta = frac{3}{5}, quad theta text{ is acute} Step 1: Find cos^2 theta = 1 – sin^2 theta= 1 – left(frac{3}{5}right)^2= 1 – frac{9}{25}= frac{16}{25} Since is acute: cos theta = frac{4}{5} Step 2: Find tan theta = frac{sin theta}{cos theta}= frac{frac{3}{5}}{frac{4}{5}}= frac{3}{4} Final Answer: cos theta = frac{4}{5}, quad tan theta =…
