The measures of the angles of the quadrilateral according the ratio

are 60°, 75°, 120° and 105°

Step-by-step explanation:

Quadrilateral is a polygon with:

1. 4 sides and 4 angles

2. The sum of the measures of its angles is 360°

The ratio of the angle measures in a quadrilateral is  4 : 5 : 8 : 7

∵ The sum of the measures of the angles of the quadrilateral  = 360°

∵ The ratio of the measures of the angle is 4 : 5 : 8 : 7

∴ The sum of their ratio = 4 + 5 + 8 + 7 = 24

- Use the ratio method to find the measure of each angle

→  angle (1)  :  angle (2)  : angle (3)  :  angle (4)  :  their sum

→  4              :  5              :  8             :  7               :  24

→  ?               :  ?              :  ?              :  ?               :  360°

- By using cross multiplication

∴ m∠(1) = [tex]\frac{(4)(360)}{24}[/tex]

∴ m∠(1) = 60°

∴ m∠(2) = [tex]\frac{(5)(360)}{24}[/tex]

∴ m∠(2) = 75°

∴ m∠(3) = [tex]\frac{(8)(360)}{24}[/tex]

∴ m∠(3) = 120°

∴ m∠(4) = [tex]\frac{(7)(360)}{24}[/tex]

∴ m∠(4) = 105°

The measures of the angles of the quadrilateral according the ratio

are 60°, 75°, 120° and 105°
