Question

in a quadrilateral three angles 55 65 150 find the fourth angle.​

Answer 1

According to the property of quadrilaterals , the sum of interior or exterior angles = 360°

therefore 55+65+150 + fourth angle = 360°

= 120+150+x = 360°

= x = 360-270°

x = 90°

$\huge{ \underline{ \underline{ \green{ \sf{ Solution\ : }}}}}$

we know in quadrilateral

the sum of all angles = 360°

Given, the measure of three angle are 55° , 65° , 150°

Let the another angle be x

therefore, 55 + 65 + 150 + x = 360 °

or, 270 + x = 360°

or, x = 360- 270 = 90°

x = 90°

the another angle of the quadrilateral is 90°
