Answer:
option 3- 5 square root 2
Step-by-step explanation:
![\sin 45° = \frac{BY}{OY} \\ \\ \frac{1}{ \sqrt{2} } = \frac{BY}{10} \\ \\ BY = \frac{10}{ \sqrt{2} } \\ \\ BY = \frac{10 \times \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } \\ \\ BY = \frac{10 \sqrt{2} }{2 } \\ \\ \huge \red{ \boxed{BY = 5 \sqrt{2} }}](https://tex.z-dn.net/?f=%5Csin%2045%C2%B0%20%3D%20%5Cfrac%7BBY%7D%7BOY%7D%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7B2%7D%20%7D%20%20%3D%20%20%5Cfrac%7BBY%7D%7B10%7D%20%20%5C%5C%20%20%5C%5C%20BY%20%3D%20%20%5Cfrac%7B10%7D%7B%20%5Csqrt%7B2%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20BY%20%3D%20%20%5Cfrac%7B10%20%5Ctimes%20%20%5Csqrt%7B2%7D%20%7D%7B%20%5Csqrt%7B2%7D%20%5Ctimes%20%20%5Csqrt%7B2%7D%20%20%7D%20%20%20%5C%5C%20%20%5C%5C%20BY%20%3D%20%20%5Cfrac%7B10%20%5Csqrt%7B2%7D%20%7D%7B2%20%7D%20%20%20%5C%5C%20%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7BBY%20%3D%20%205%20%5Csqrt%7B2%7D%20%7D%7D)
Answer:
z = -1
Step-by-step explanation:
3(z + 5) = 12
Step 1: Divide both sides by 3.
z + 5 = 4
Step 2: Subtract 5 from both sides.
z = -1
