Given that ∠a≅∠b , gavin conjectured that ∠a and ∠b are complementary angles. which statement is a counterexample to gavin 's conjecture? m∠a=30° and m∠b=60° m∠a=25° and m∠b=25° m∠a=45° and m∠b=45° m∠a=10° and m∠b=15°

complementary angles are angles that add up to 90º

45º+45º=90º

thus making m∠A=45º and m∠B=45º the correct answere

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
