Assume each square is 1 unit.
The base of the large triangle is 6 units and the base of the smaller triangle is 3 units.
The scale factor is 1/2
Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴
= 
∴ x = 3
∴ The value of x is 3
So just add all of them together and you get 405. Then divide by the amount of numbers there is which is 5. So 405 divided by 5. The answer is 81.
