PLEASE HELP. ANYONE PLEASE​

Answer 1

Therefore, y = 12.3 cm

Explanation:

Given:

Hypotenuse = 15 cm

Adjacent Side of ∠ 35° = y

Side opposite to ∠ 35° = x

To Find :

y = ?

Solution:

In Right Angle Triangle we have Cosine Identity as,

`\cos 35 = \frac{\textrm{side adjacent to angle 35}}{Hypotenuse}\\`

Substituting the values we get

`\cos 35 = (y)/(15)\\`

`\therefore y =15* \cos 35\\\\\therefore y =15* 0.819\\\\\therefore y =12.2865\\\\\therefore y =12.3\ cm\ \textrm{Round to nearest tenth}`

Therefore, y = 12.3 cm
