the angle of quadrilateral are in the ratio 2:3:6:7 what is the measure of its smallest angle
Answers
AnswEr :-
- Smallest angle of the quadrilateral is 40°.
Given :-
- The angles of quadrilateral are in the ratio 2:3:6:7.
To Find :-
- Measure of the smallest angle.
SoluTion :-
Put x in the ratio
Now, angles are
- 2x
- 3x
- 6x
- 7x
We know that the sum of all angles of a quadrilateral is 360°.
According to question :-
2x + 3x + 6x + 7x = 360
→ 5x + 13x = 360
→ 18x = 360
→ x = 360/18
→ x = 20
Now,
Angles are
- 2x = 2 × 20 = 40°
- 3x = 3 × 20 = 60°
- 6x = 6 × 20 = 120°
- 7x = 7 × 20 = 140°
Verification :-
40° + 60° + 120° + 140° = 360°
→ 100° + 120° + 140° = 360°
→ 260° + 100° = 360°
→ 360° = 360°
Verified
Hence, the smallest angle of the quadrilateral is 40°.
