Question

maths do the following question with example

Answer 1

Given:-

• A quadrilateral is given to us .
• There are 3 known angles and one unknown angle.

To Find:-

• The value of x .

Soluⁿ :-

We know that angle sum property of a quadrilateral is 360°. So , here sum of all the angles will be 360° .

Atq ,

➥ 120° + 106° + 62° + 4x = 360°.

➥ 288° + 4x = 360°.

➥ 4x = (360-288)° .

➥ 4x = 72° .

➥ x = 72°/4.

➤ x = 18° .

Hence the value of x is 18° .

Answer 2

62+120+106+4x=360(as the sum of all the interior angles of quadrilateral is 360°)

288+5x=360

4x=360-288

4x=72

x=72/4

x=18

therefore 4x=18*4

4x=72
