Question

The three angles of a quadrilateral are 50°, 75° and 105º. Find its fourth angle.​

Answer 1

Answer:

130°

Step-by-step explanation:

we know the sum of all angle of a quadrilateral is 360°

so

let the fourth angle be x

x+50+75+105=360°

x+230=360

x=360-230

x=130°

if it is correct then mark it as brainiest

Answer 2

Sum of interior angles of quadrilateral = 360 degree

x+ 50+75+105 = 360

x+230 = 360

x = 360-230

x = 130
