Angle a and angle b are supplementary angles. the ratio of the measure of angle a to the measure of angle b is 5: 4. find the measures of angle a and angle b.

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
