In the adjacent figure, BDE is a triangle in which EB is produced to F and DB is produced to G. If `/_DBE=x^(@)=/_FBG=(x+2)^(@)` and `/_BED=(x+7)^(@)`, then the value of x is |

Answer» (a) Vertically opposite angles are equal. Sum of the angles of a triangle is `180^(@)`. (b) `/_FBG=/_DBE` as they are vertically opposite angles. (c ) Sum of three angle of `Delta DBE` is `180^(@)` . Use this to find the required angle. |
