Please my nairalander,i know we have been a little busy a whole day before now and we must have been tired before now but there is a little problem I have here and right now.. I know we have mathematicians here and that I want to congratulate yu all mathematicians who are willing to help.. Please I want to find (x) in this given angle below. I'm so tired finding this alone Thank you lalasticlacla

55+40+x = 180 x = 85 degree in d second triangle,vertically opp angle = 85 degree sum of angle in a triangle; 85+20+x = 180 x = 75 degree then x = 75 degree vertically opposite angle option c is the correct and |

Ahaa, Olodo nie ni?? x na 40 joo, u no even need calculation self.
∆ABC = ∆EGF.
Cant u see dat line BA is parallel to GE ?? 1 Like |

NDSMELODY:I disagree Sir, i tink d question is nt corect, pls try to use alternate angle method to solve it. i tink d question is wrong |

the question is not correct athernate angle is not satisfied when it has parallel line and a transversal |

PROFdanmike:question is incorrect. If  = 55°, then angle D must also be 55° and x be 40°. You need no pen or paper for this |

Nothing is wrong with d question..any one with explanatory solution shld post it...poster of d questn shld pls correct d work if there is any error but if otherwise 75 degree is d ans then |

NDSMELODY:The maths bosses has spoken, you still day argue?. Even a JSS1 student can detect the error in that question. |

Sorry bro,it is true |

NDSMELODY:This question was set by someone with no sound knowledge of basic geometry. Since alternate interior angles are congruent, ∠BAD ≅ ∠ADE and ∠ABC ≅ ∠BGD Given this, it's incorrect to state that m(∠BAD) ≠ m(∠ADE) Either the measures of both angles is 55° or 20°, ie. either m(∠BAD) = m(∠ADE) = 55° or m(∠BAD) = m(∠ADE) = 20°. Choose one. If m(∠ABC) = 40°, then m(∠BGD) = 40°. Since vertical angles are congruent, then ∠BGD ≅ ∠EGF This means that m(∠BGD) = m(∠EGF) = 40° A shortcut approach is to observe that ∠ABC and ∠EGF are corresponding angles and corresponding angles are congruent. This means that∴ m(∠EGF) = 40° OPTION A is the answer |
