Answer» Given : ∠ABC = 60°and CB be produced to the point D. Now, BX is a ray from B and the point X lies on that side of DC where A lies and ∠ABX ∶ ∠DBX = 5 ∶ 7. To find : (i) ∠CBX (ii) ∠DBX (III) REFLEX ∠ABX. Solution: ∠ABC = 60° CB be produced to the point D. => ∠ABC and ∠ABD form a LINEAR PAIR => 60° + ∠ABD = 180° => ∠ABD = 120° ∠ABD = ∠ABX +∠DBX = 120° ∠ABX ∶ ∠DBX = 5 ∶ 7. => ∠ABX = 50° , ∠DBX = 70° ∠CBX = ∠ABC + ∠ABX => ∠CBX = 60° + 50° = 110° Reflex ∠ABX. = 360° - ∠ABX = 360° - 50° = 310° learn More: in the given figure. find the value of reflex angle por - Brainly.in In figure,angle ABC=120^0,where A,B and c are points on the CIRCLE ... |
