Question

In a right angle triangle length of base is 4cm and perpendicular component is 3cm find sin theta,cos theta,tan theta

Answer 1

Explanation:

sin theta = opposite /hypotenuse

cos theta =adjecant /hypotenuse

(hypotenuse)^2= (base)^2+(perpendicular component)^2

(4)^2+(3)^2=16+9=25

hence hypotenuse =5cm

hence sin theta =4/5

cos theta=3/5

than theta= sin theta/cos theta =4/3
