Question

A right triangle contains another angle of 35 degrees. Opposite thatangle is a side measuring 9cm. Using trigonometric ratios, find the lengthof the side adjacent to that 35-degree angle (not the hypotenuse).*08.43cmO 11.67cm12.85cm15.60cm

Answer 1

According to the given data we have the following:

right triangle contains another angle=x

Opposite that angle is a side measuring 9cm

Therefore, to find the length of the side adjacent to that 35-degree angle we would have to make the following calculation:

sin 35=9cm/x

x=9cm/ sin 35

x=15.60 cm

Therefore, the length of the side adjacent would be of 15.60 cm.
