Question

A quadrilateral has 3 acute angles each
measures 80°. What is the measure of an angles?​

Answer 1

Answer :

• fourth angle is 120⁰

Given :

• A Quadrilateral has 3 acute angles each measures 80⁰

To find :

• The measures of an angle

Solution :

As we know that ,

• Sum of all angles in a Quadrilateral is 360⁰

Given that, A Quadrilateral has 3 acute angles then 80 , 80 , 80

Now ,

• Let the fourth angle be x

Sum of all angles in a Quadrilateral is 360⁰ then ,

↝ 80 + 80 + 80 + x = 360

↝ 240 + x = 360

↝ x = 360 - 240

↝ x = 120⁰

Hence , fourth angle is 120⁰

More Explanation :

• Quadrilateral is a plane figure
• Quadrilateral has four sides
• Quadrilateral has also have four vertices
• Trapezium , square , rectangle, kite , parallelogram are types of Quadrilateral
• Sum of angles in a Quadrilateral is 360⁰

Answer 2

Answer:

Answer :

fourth angle is 120⁰

Given :

A Quadrilateral has 3 acute angles each measures 80⁰

To find :

The measures of an angle

Solution :

As we know that ,

Sum of all angles in a Quadrilateral is 360⁰

Given that, A Quadrilateral has 3 acute angles then 80 , 80 , 80

Now ,

Let the fourth angle be x

Sum of all angles in a Quadrilateral is 360⁰ then ,

↝ 80 + 80 + 80 + x = 360

↝ 240 + x = 360

↝ x = 360 - 240

↝ x = 120⁰

Hence , fourth angle is 120⁰

More Explanation :

Quadrilateral is a plane figure

Quadrilateral has four sides

Quadrilateral has also have four vertices

Trapezium , square , rectangle, kite , parallelogram are types of Quadrilateral

Sum of angles in a Quadrilateral is 360⁰
