Answer:
Θ = 124°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n - 5, thus
sum = 180° × 3 = 540°
Sum the given interior angles and equate to 540
2x - 3 + 2x + 7 +3x - 4 + 3x - 4 + 3x - 2 = 540, that is
13x - 6 = 540 ( add 6 to both sides )
13x = 546 ( divide both sides by 13 )
x = 42
Thus
Θ = 3x - 2 = 3(42) - 2 = 126 - 2 = 124°
Answer:
x =14
The left angle is 110
The right angle is =70
x = 58
Step-by-step explanation:
x+96 +5x = 180 because the two angles add together to form a straight line
Combine like terms
6x +96 = 180
Subtract 96 from each side
6x+96-96 = 180-96
6x =84
Divide by 6
6x/6 = 84/6
x =14
The left angle is x+96 = 14+96 = 110
The right angle is 5x =6*14 =70
2. 2x+4 = 120 since they are vertical angles
Subtract 4 from each side
2x+4-4=120-4
2x = 116
Divide by 2
2x/2 =116/2
x = 58
