Question

three angles of a quadrilateral are 115, 50, 68. Find the fourth angle.

​

Answer 1

Step-by-step explanation:

fourth angel= 360-115-50-68

= 360-233

= 127

Answer 2

Solution

We have given three angles of a quadrilateral $115^{\circ},50^{\circ},68^{\circ}$

We have to find out the fourth angle ?

As we know that quadrilateral having four angles which together makes sum equals to $360^{\circ}$

Let us assume that the fourth angle be 'X'

=>By applying angle sum property of Quadrilateral

$115^{\circ}+50^{\circ}+68^{\circ}+x=360^{\circ}$

$\longmapsto233 + x = 360$

$\longmapsto \: x = 360 - 233$

$\sf\bold{\boxed{x = 127^{\circ}}}$

$\sf \therefore \: the \:fourth \:angle \:is\:127^{\circ}$

If we add above all the angles it makes $360^{\circ}$.

Extra information=>

Quadrilateral is a solid figure / 2D figure having four sides ,four vertex and four angles.

Various Quadrilateral figures are square, rectangle,rhombus,kite , parallelogram and trapezium etc.
