Question

Find the value of x if x 2 X + 13 degree 3 X + 10 degree and x minus 6 degree are all the angles of a quadrilateral

Answer 1

Answer:

49 degree

Step-by-step explanation:

sum of all angle of a quadrilateral is 360°

x+2x+13+3x+10 + x -6 = 360°

7x + 17 360°

7x = 360° - 17

7x = 343

x = 49°

Answer 2

Answer:

sum of angle =360degree

x(2x+13) + (3x+10(x-6) ) =360degree

or, x+2x+3x+x+13+10-6=360degree

or, 7x+17=360degree

or, 7x=360-17= 343

or, x= 343/7

x= 49 degree
