Solution :
Let the 3rd angle be 5x and 4th angle be 8x
★ Sum of all angles of Quadrilateral = 360°
According to the question :
→ 190° + 40° + 5x + 8x = 360°
→ 230° + 13x = 360°
→ 13x = 360° - 230°
→ 13x = 130°
→ x =
→ x = 10°
Fourth angle = 5(10) = 50° and Fifth angle = 8(10) = 80°
Verification :
★ Sum of all angles of Quadrilateral = 360°
→ 190° + 40° + 5(10) + 8(10) = 360°
→ 230° + 50° + 80° = 360°
→ 280° + 80° = 360°
→ 360° = 360°
Hence,Verified!
