Answer:
119°
Step-by-step explanation:
the angles of a triangle make 180° (so does a straight line) therefore
180 (triangle) = a + c + 51
to find c:
180 (straight line) = 112 + c
c = 180 - 112
c = 68°
now we have
180 (triangle) = a + 68 + 51
to find a:
a = 180 - (68 + 51)
a = 180 - 119
a = 61°
to find b:
180 (straight line) = 61 + b
b = 180 - 61
b = 119°
Answer:
134°
Step-by-step explanation:
The sum of interior angles of a regular polygon is: (n - 2)180
Hexagon has six sides, n is 6
Sum of it's angles is (6 - 2)180 = 720
sum of our hexagon:
119 + 129 + 104 + 139 + 95 + x = 720°
x is 134°
