What is the value of x?

Mathematics
1 answer:
mixas84 [53]4 years ago
8 0

For a convex polygon with n sides, the sum of interior angles is (n-2)·180°. Thus, the sum of interior angles of a pentagon is (5-2)·180° = 540°.

... x° + 131° + 108° + 107° + 110° = 540°

... x° = 84° . . . . . . subtract 456° from both sides.

The value of x is 84.

satela [25.4K]

Answer:

<2 = 129°

Step-by-step explanation:

if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°

2x + 14 + 5x + 12 = 7x + 26 =180°

7x = 154 ➡x = 21°

m <2 = 5×21 + 14

Correct
____ [38]
  • Answer:

<em>v₂ = 55mph</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em>Velocity formula</em>

<em>v = distance/time = d/t => d = vₓt</em>

<em>v₁ = v₂ - 11</em>

<em>t₁ = 10h</em>

<em>t₂ = 8h</em>

<em>d = v₁ₓt₁ = (v₂ - 11)t₁ </em>

<em>d = v₂t₂</em>

<em>(v₂ - 11)t₁ = v₂t₂</em>

<em>replace t₁ ; t₂</em>

<em>(v₂ - 11)10 = v₂8</em>

<em>10v₂ - 11ₓ10 = 8v₂</em>

<em>10v₂ - 8v₂ = 110</em>

<em>2v₂ = 110</em>

<em>v₂ = 55 mph</em>

<em>Good luck !</em>
