Question

HELP 10 MIN LEFT!!!!

Answer 1

Answer: 16.3 in.

Explanation:

use SOH CAH TOA

cos x = adj/hyp

cos 25 = y/18

18 cos 25 = y

y= 16.3

Answer 2

To one decimal place,

y = 16.3 m

Explanation:

Using SOHCAHTOA,

In this case we need to use CAH,

WE know the angle = 25 and the hypotenuse H = 18,

so,

y = adjacent

`cos(angle) = y/H\\y = (18)(cos(25))\\y = 16.3135\\y = 16.3`
