Here triangle ABC is a special triangle because one of its angle measures 30º which implies that the angles

of the triangle are in the form of 30º-60º-90º.

The trigonometric function, sin(C) = (opposite side)/ (hypotenuse) = AB/AC

This gives: sin(30)= AB/ 6==>1/2= AB/ 6==> AB= 6 * 1/2

Here triangle PQR is a special triangle because one of its angle measures 45º which implies that the angles

of the triangle are in the form of 45º-45º-90º.

The trigonometric function, tan(R) = (opposite side)/ (adjacent side)= PQ/QR

This gives: tan(45)= 5/ QR==>1= 5/ QR==>QR= 1* 5
