The angles of a quadrilateral are in the ratio of 2:3:5:8. Find the angles of the quadrilateral.
Answers
The ratio of angles of quadrilateral are 2:3:5:8
⇒ Let the four angles be 2x,3x,5x and 8x.
We know, sum of four angles of quadrilateral is 360°
∴ 2x + 3x + 5x + 8x = 360°
⇒18x = 360°
⇒ x = 20°
The angles are,
⇒ 2x = 2×20° = 40°
⇒ 3x = 3×20 = 60°
⇒ 5x = 5×20 = 100 °
⇒ 8x = 8×20° = 160°
∴ The smallest angle of the quadrilateral is 40°.
Given :-
The angles of a quadrilateral are in the ratio of 2 : 3 : 5 : 8.
To Find :-
What are the angles of the quadrilateral.
Solution :-
Let, the first angles be 2x
Second angles be 3x
Third angles be 5x
And, the fourth angles will be 8x
As we know that,
★ Sum of angles of quadrilateral = 360° ★
According to the question by using the formula we get,
Hence, the required angles are,
✧ First angles = 2x = 2(20°) = 40°
✧ Second angles = 3x = 3(20°) = 60°
✧ Third angles = 5x = 5(20°) = 100°
✧ Fourth angles = 8x = 8(20°) = 160°
