Question

The measures of three angles of a
quadrilateral are 120 130 and 50
Find the measure of fourth angle​

Answer 1

Answer:

60°

Step-by-step explanation:

Angle Sum Property of Quadrilateral = 360°

=> angle 1 + angle 2 + angle 3 + angle 4 = 360°

=> 120 + 130 + 50 + angle 4 = 360

=> 300 + angle 4 = 360

=> angle 4 = 360 - 300 = 60°

Answer 2

Answer:

Step-by-step explanation:

Sum of angles in a Quadrilateral =360 degrees

Here,we know the 3 angles

a = 120

d=130

c=50

and d = ?

So,

a+b+c+d =360

120+130+50+d=360

300+d=360

d=360-300

d=60

Therefore,the 4th of the Quadrilater is 60 degrees
