Question

the three angle of a qudrillateral are 70°, 65° and 110°. find the fourth angle​

Answer 1

Answer:

we know that sum of all angles of a quadrilateral is always 360⁰

Let the 4th angle be x,

70⁰+65⁰+110⁰+x=360⁰

245⁰+x=360⁰

x=360⁰-245⁰

x=115⁰

Therefore the fourth angle is of 115⁰

Answer 2

Answer:

Let the fourth angle be x.

70°+65°+110°+x =360°

245°+x=360°

x=360°-245°

x=115°
