Question

If the three angles of a quadrilateral are 120, 130, 100 then what is the fourth angle? 30 b. 10 c. 40 d. 90

Answer 1

Answer:

10 is the answer of this question

Answer 2

Answer:

b) 10

Step-by-step explanation:

The sum of angles of a quadrilateral is 360°.

Let the 4th angle be x

So,

360°= 120°+130°+100°+x

360°= 350°+x

x=360°-350°

x = 10°.
