Question

The three angles of quadrilateral are 90⁰ 60⁰ and 120⁰
Find the fourth angle

Answer 1

Let fourth angle be x

90+60+120+x=360

x=360-270

x=90

Fourth angle is 90°

Answer 2

Answer:

The fourth angle is 90⁰

Step-by-step explanation:

We know that the sum of all angles of a quadrilateral is 360⁰

Angle 1 =  90⁰

Angle 2 = 60⁰

Angle 3 = 120⁰

So the fourth angle will be --> 360⁰- (90⁰+60⁰+120⁰)

                                            --> 90⁰

So, we can find the answer using angle sum property of a Quadrilateral
