Question

I really need help with this Triangle problem. ​

Answer 1

12

Explanation:

Here we use SOHCAHTOA

Seeing as we have the hypotenuse and we are working to find out the opposite, we use SOH

Sin(x)= Opposite/Hypotenuse

Sin(45) = x/
`12√(2) \\`

×12 root 2

sin(45) times 12 root 2= 12

x=12
