Answer» ANSWER : The fourth angle of a quadilateral is Explanation : We are given with the three angles of a quadrilateral, that is, 100°, 98°, 92°. We have to find out the fourth angle of a quadrilateral. ⠀_________________________ Now, Let us assume that, the fourth angle of a quadrilateral is "x" $.$ We know that, if we are given with the three angles of a quadrilateral then we have the required formula, that is, ⠀ ⠀ → The sum of all four angles of a quadrilateral is 360°. This statement is known as 'angle sum property of a quadrilateral'. ⠀ ⠀ Substituting the given VALUES in the formula, ⇒ 100 + 98 + 92 + x = 360 ⇒ 198 + 92 + x = 360 ⇒ 290 + x = 360 ⇒ x = 360 - 290 ⇒ x = 70 Hence, the fourth angle of a quadrilateral is 70°.

Answer»

ANSWER :

The fourth angle of a quadilateral is

Explanation :

We are given with the three angles of a quadrilateral, that is,

100°, 98°, 92°.

We have to find out the fourth angle of a quadrilateral.

⠀_________________________

Now,

Let us assume that, the fourth angle of a quadrilateral is "x" $.$

We know that, if we are given with the three angles of a quadrilateral then we have the required formula, that is,

⠀

→ The sum of all four angles of a quadrilateral is 360°. This statement is known as 'angle sum property of a quadrilateral'.

⠀

Substituting the given VALUES in the formula,

⇒ 100 + 98 + 92 + x = 360

⇒ 198 + 92 + x = 360

⇒ 290 + x = 360

⇒ x = 360 - 290

⇒ x = 70

Hence, the fourth angle of a quadrilateral is 70°.
