Answer:
∠ C = ∠BCD = 30°
Step-by-step explanation:
∠ EDF = ∠GFC = 110° [ corresponding angles ]
Now consider triangle BCF
∠FBC + ∠ABC = 180° [ straight line angle ]
∠FBC + 100° = 180°
∠FBC = 180 - 100 = 80°
∠BFC + ∠GFC = 180° [ straight line angle ]
∠BFC + 110° = 180°
∠BFC = 180 - 110 = 70°
Sum of angles of triangle is 180°
Therefore , in triangle BCF
That is ,
∠F + ∠B + ∠ C = 180°
70° + 80° + ∠C = 180°
∠C = 180 - 150 = 30°
Given a triangle (3 sides), a hexagon (6 sides) and a nonagon (9 sides).
The sides increases by 3 and the equation that represents the pattern is 3n.
Therefore, the <span>expression that represents the number of sides in the polygon for the nth member of the pattern is 3n.</span>
Answer:
a=2
b=14
Step-by-step explanation:
One can be 7/2 ...................
I think the answer is 3.5 cause when you divide it 7 go inside and 7 there's nothing you can multiply to get 7
