Question

the measure of three angle of a quadrilateral are 39,141and67 ,the Fourth angle is​

Answer 1

Given :

the measure of three angle of a quadrilateral are 39, 141 and 67

To find :

Forth angle

Solution :

Let the forth angle be x

➸ 39° + 141° + 67° + x = 360°

➸ 247° + x = 360°

➸ x = 360° - 247°

➸ x = 113°

∴ Forth angle of a quadrilateral is 113°

Answer 2

Answer:

The fourth angle is 113 degree.

Step-by-step explanation:

Given,

Measures of angles =39 degree,141 degree and 67 degree.

Sum of all the angles of a quadrilateral = 360 degree

Measure of fourth angle = ?

Let the fourth angle is equal to 'x'

39+141+67+x= 360

247+x=360

x=360 - 247

x= 113

Therefore, the measure of fourth angle = 113 degree.
