Answer:
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:
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:
None of the choices is correct
