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°
Answer:
Movies are $4.67 each and Video Games are $5.22 each
Step-by-step explanation:
M=Movies, V=Video Games
5M+3V=39
2M+12V=72
You can either use substitution or elimination.
2 1/6 - (-8/3) - 4 7/9 = 2 1/6 + 2 2/3 - 4 7/9 = (3 + 12 - 14)/18 = 1/18
