the answer is 75 degrees. considering triangle ABC, (sum of angles in a triangle is 180 degrees) therefore angle ACB = 85 degrees angle ACB = angle DCG (alternate angles) Therefore angle DGC = 75 degrees (sum of angles in a triangle is 180 degrees) angle EGF = x = 75 degrees (alternate angles) 3 Likes |

Sum of angle in a triangle is 180...therefore angle ABC =180 ....AB= 55+40=95.....To get C 180-95=75 .....C is therefore 75 |

x is 400 Corresponding angles are equal. <ABC = 400 <EGF = x0 <ABC corresponds to <EGF Hence x0 = 400 2 Likes |

After thorough calculation, I got 175. My answer isn't even on the option list. I'm a lawyer. |

yoddy:Some places where you mentioned alternate angles is actually meant to be vertically opposite. |

Not that hard: 75 |

Darivie04:Thanks. You're right |

Gurumaharaji:How was your 180-95=75 ? |

x = 40deg. (corresponding angles are equal) though your diagram is not correct. <A should be equal to <D. Cos they are alternate angles |
| Re: Mathematicians In The House Should Solve This Problem by beeblack: 6:04pm On Jul 16, 2019 |
Answer= 75deg. N:B= Angle ACB= DCG (opposite angle, not alternate angle) |

Hello, the diagram is wrong though that 20° should be 55° or vice vicsa <A should be equal to angle <D (alternate angles) |
