Answer:

100° and 80°

Step-by-step explanation:

Ratio means they are sort of multiples of a certain number (which I used X) and A is 5 times X and B is 4 times X. Since they are supplementary they sum 180°. After summing up both angles and equaling them to 180°, solve for X and substitute in the original equations
