Sagot :

Answer:

∠RYF =  68º

Step-by-step explanation:

The angles are supplementary

(4c + 72) + (5c + 18) = 180

Combine like terms

9c + 90 = 180

Subtract 90 from both sides

9c = 90

Divide both sides by 9

c = 10

-----------------------

∠RYF = 5c + 18

∠RYF = 5(10) + 18

∠RYF = 50 + 18

∠RYF =  68
