Answer 1

Q 1

Sum of interior angles of a pentagon:

• 4x + 60 = 180(5 - 2)
• 4x + 60 = 540
• 4x = 480
• x = 120

Q 6

Midsegment is half of the sum of the bases:

• (2n - 2 + 4n + 6)/2 = n + 12
• (6n + 4)/2 = n + 12
• 3n + 2 = n + 12
• 2n = 10
• n = 5

Midsegment is:

• 5 + 12 = 17

Correct choice is D

Q 3

• m∠1 = 90 as diagonals are perpendicular
• m∠2 = 41 as alternate interior angles

∠3 is complementary with ∠2:

• m∠3 = 90 - 41 = 49

None of the choices is correct
