Question

The three angles of a Quadrilateral are 55 degree,65 degree and 105 degree.what is the fourth angle?

Answer 1

Answer:

w.k.t

sum of all angle =360

55 +65+105 + d =360

d=135

Answer 2

Question :-

• The three angles of a quadrilateral are 65 ,55 ,130 degree. Find its fourth angle

Given :-

• Three angles of quadrilateral are 65° , 55° , 130°

To Find :-

• Fourth angle of quadrilateral

† Note

• Sum of all the interior angles of quadrilateral is 360°

Solution :-

Let,

• The fourth angle be x

→ 65 + 55 + 130 + x = 360

→ 120 + 130 + x = 360

→ 250 + x = 360

→ x = 360 - 250

→ x = 110°

Hence

• The fourth angle of quadrilateral is 110° $\:\:$
