Point c is the center of the circle. the measure of angle a b c is 3x + 120. arc ab measures 65x - 4. find the measure of arc ab

How do i do this using elimination 2x+3y=12 x-y=6

Which statement justifies why angle ebc measures 90?

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′.
