If angle∠ a and angle∠ b are supplementary angles and angle∠ a is 18 times as large as angle∠ b, find the measures of angle∠ a and angle∠ b.

Write the following as a base and exponent

Factor the expression using gcf 9b+45

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
