Question

Three angles of a quadrilateral are
83°,490,67° . Find the measure of the
fourth angle.​

Answer 1

Answer:

Measure of fourth angle is 161°

Step-by-step explanation:

As sum of all angles of a quadrilateral measure 360°,

Let the fourth angle be x ,

83+49+67+x=360

199+x=360

x=360-199

x=161°

Answer 2

Answer:

angle sum property of quadrilateral = 360⁰

83⁰ + 49⁰ + 67⁰ + fourth angle = 360⁰

fourth angle = 360⁰- 199⁰

fourth angle = 161⁰
