Answer:
106
Step-by-step explanation:
Bring the values to one side and change the signs
Always substitute in brackets
_=136+(-30)
106=136-30
Thus your answer is 106

Step-by-step explanation:
Answer:
sin(A) = cos(C)
Step-by-step explanation:
Trig ratios:
![\mathsf{\sin(\theta)=\dfrac{O}{H} \ \ \ \cos(\theta)=\dfrac{A}{H} \ \ \ \tan(\theta)=\dfrac{O}{A}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Csin%28%5Ctheta%29%3D%5Cdfrac%7BO%7D%7BH%7D%20%5C%20%5C%20%5C%20%5Ccos%28%5Ctheta%29%3D%5Cdfrac%7BA%7D%7BH%7D%20%5C%20%5C%20%5C%20%5Ctan%28%5Ctheta%29%3D%5Cdfrac%7BO%7D%7BA%7D%7D)
(where
is the angle, O is the side opposite the angle, A is the side adjacent to the angle, H is the hypotenuse, of a right triangle)
![\mathsf{\sin(A)=\dfrac{BC}{AC}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Csin%28A%29%3D%5Cdfrac%7BBC%7D%7BAC%7D%7D)
![\mathsf{\cos(C)=\dfrac{BC}{AC}}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Ccos%28C%29%3D%5Cdfrac%7BBC%7D%7BAC%7D%7D)
Therefore, sin(A) = cos(C)
