Question

find the measure of largest angle of a quadrilateral if the measures of its interior angle are in the radius of 3:4:5:6​

Answer 1

Answer:

120 degrees

Step-by-step explanation:

Ratio = 3:4:5:6

Sum = 3x + 4x + 5x + 6x = 18x

= 18x = 360

x = 20

Measure of 1st angle = 3 × 20

= 60

Measure of 2nd angle = 4 × 20

= 80

Measure of 3rd angle = 5 × 20

= 100

Measure of 4th angle = 6 × 20

= 120

So 120 degrees is the largest angle
