Question

four angle of quadilatreal are ( x+10) ,(x+20) , ( x+30) , ( x + 40 )​

Answer 1

The sum of the angles of a quadrilateral is equal to 360 degrees.

x + x + 10 + x + 20 + x + 30 = 360

Combine like terms and solve.

4x + 60 = 360

4x = 300

x = 75

The measurement of the angles are:

x = 75 degrees

x + 10 = 85 degrees

x + 20 = 95 degrees

x + 30 = 105 degrees

You can check this by adding your 4 angle measurements.

75 + 85 + 95 + 105 = 360

Answer 2

Answer:

X=65degree

X+10 =75degree

X +20 =85degree

X +30 =95degree

X+40 =105degree
