Aprince picked a basketful of golden apples in the enchanted orchard. on his way home, he was stopped by a troll who guarded. the troll demanded payment of 1/2 of the apples plus two more. the prince gave him the apples and set off. a little further on, he was stopped by a second troll guard who demanded a payment of 1/2 of the apples the prince now had plus two more. the prince paid and set off again. just before leaving the orchard, a third troll stopped him demanding 1/2 of his remaining apples plus two more. sadly, the prince paid him and went home. he had only two golden apples left. how many apples had he picked?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

594 square inches

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
