Question

The Angel's of the quadrilateral are in the ratio 1.2.3.4 find the biggest angle.

Answer 1

HERE'S THE ANSWER

Let the measure of angles be x,2x,3x and 4x.

We know that sum of measure of all four angles is 360

o

.

∴ x+2x+3x+4x=360

o

⇒ 10x=360

o

⇒ x=36

o

⇒ 2x=2×36

o

=72

o

⇒ 3x=3×36

o

=108

o

⇒ 4x=4×36

o

=144

o

⇒ The measures of angles of quadrilateral are 36

o

,72

o

,108

o

and 144

o

.

⇒ We can see measure of all 4 angles are different so, the given quadrilateral is trapezium.
