# If the measures of the angles of a quadrilateral are in the ratio of 3:4:5:6, find the measure of each angle.

To determine

To find:

The measures of angles of a quadrilateral.

Explanation

Approach:

1) According the property of ratios, unknown quantities in the ratio a:b:c:d should be represented by ax, bx, cx and dx.

2) The angle sum property of quadrilateral states that the sum of the angles of a quadrilateral is 360Â°.

Calculation:

It is given that the measures of the angles of a quadrilateral are in the ratio of 3:4:5:6.

Use the property of ratios.

Let the measures of the angles of a quadrilateral are 3x, 4x, 5x and 6x.

Use the angle sum property of quadrilateral.

âˆ´3x+4x+5x+6x=360<
