Answer:
The measure of each angles are 18°, 72°, 108° and 162°
Step-by-step explanation:
The angles of a quadrilateral are in the ratio 1:4:6:9
Let the common multiple be x.
∴ The angles are x, 4x, 6x and 9x
Sum of the angles of a quadrilateral = 360° ....... Formula
x + 4x + 6x + 9x = 360°
20x = 360°
x = 360°/20
x = 18
Substituting x = 18, we get,
x = 18°
4x = 4 (18) = 72°
6x = 6 (18) = 108°
9x = 9 (18) = 162°

☆ Solution ☆
Given :-
- The angles of a quadrilateral are in the ratio 1:4:6:9.
To Find :-
- The measure of each of the four angles.
Step-by-Step-Explaination :-
Let the angles be 1x, 4x, 6x and 9x
As we know that :-
The sum of all angles of quadrilateral = 360°
So,
1x + 4x + 6x + 9x = 360°
20x = 360°
x = 360/20
x = 18°
Thus,
The measures of each angles of quadrilateral are :-
1x = 1 × 18° = 18°
4x = 4 × 18° = 72°
6x = 6 × 18° = 108°
9x = 9 × 18° = 162°
Hence,
The angles are 18°, 72°, 108° and 162°.
