Answer:

1) 120° 2) 98° 3) 104° 4) 140°

Step-by-step explanation:

1) add the two angles together then set them equal to 180 then solve for x. Once x is found plug it in for ∠A

2) set the two angles equal to each other then solve for x. once x is found plug it in for ∠B

3) set the two angles equal to each other to find x. once x is found plug it in for ∠C

4) add the two angles together then set it equal to 180. solve for x. once x is fould plug it in for ∠D

Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjectur

iren2701 [21]

Answer:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240

Hence proved Conjecture is correct

L.H.S=R.H.S

Step-by-step explanation:

Consider the pattern:

8(5)=10(5-1)=40

8(5) + 8(25) = 10(25 - 1) =240

8(5) + 8(25) + 8(125) = 10(125 - 1) =1240

8(5) + 8(25) + 8(125) + 8(625) = 10(625 - 1)=6240

According to inductive reasoning next term of pattern will become:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240

Checking whether conjecture is correct or not:

Consider L.H.S:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)

40+200+1000+5000+25000

31240

R.H.S:

31240

Hence proved Conjecture is correct

L.H.S=R.H.S
