Answer:
17
Step-by-step explanation:
2c + d^3 - 3e +4f
=2(3) + (5^2) - 3(6) + 4(1)
=6+25-18+4
=17

Answer:
<h3>Q 1</h3>
<u>Sum of interior angles of a pentagon:</u>
- 4x + 60 = 180(5 - 2)
- 4x + 60 = 540
- 4x = 480
- x = 120
<h3>Q 6</h3>
<u>Midsegment is half of the sum of the bases:</u>
- (2n - 2 + 4n + 6)/2 = n + 12
- (6n + 4)/2 = n + 12
- 3n + 2 = n + 12
- 2n = 10
- n = 5
<u>Midsegment is:</u>
Correct choice is D
<h3>Q 3</h3>
- m∠1 = 90 as diagonals are perpendicular
- m∠2 = 41 as alternate interior angles
<u>∠3 is complementary with ∠2:</u>
None of the choices is correct
Answer:
<1 and <6 = 98
<2 and <3 = 139
<4 and <5 = 123
Step-by-step explanation:
82 + 9x - 6 + 6x - 1 = 180
15x + 75 = 180
15x = 105
x = 7
<1:
x + 82 = 180
x = 98
<2:
6x - 1 = 6(7) - 1 = 41
x + 41 = 180
x = 139
<3 = <2 because of vertical angle thm so <3 = 139
<5:
9x - 6 = 9(7) - 6 = 57
x + 57 = 180
x = 123
<4 = 5 because of vertical angle thm
<6 = <1 because of vertical angle thm
