Question

the size of angle of a quadrilateral are x, x+10, x+20, and x+30 degrees. Find the measure of each angle.

Answer 1

the sum of angles = 360 degrees
so
x + x +10 +x+20+x+30 = 360
4x + 60 = 360
4x = 300
x = 75 degrees
angles are 75, 85, 95 and 105 degrees

Answer 2

ok with that?

Answer 3

did you follow the method?

Answer 4

may be plss tell me in short

Answer 5

if you add up the four angles in any quadrilateral the total is 360 degrees.
you gave the values of the 4 angles in terms of
so adding these and putting them = to 360 gives our equation
which we had to solve for x
did u understand the steps of the solution?

Answer 6

ok..

Answer 7

good - bring all terms in x to one side and numbers on the right
