Question 904539
let one of the angles be equal to x.
the other angle that's equal to it is also equal to x.
the third angle is equal to the sum of the two equal angles so the third angle is equal to 2x.
the fourth angle is equal to 75.
the sum of the angles in a quadrilateral is 360 degrees.
you get x + x + 2x + 75 = 360
combine like terms to get 4x + 75 = 360
subtract 75 from both sides of the equation to get 4x = 285
divide both sides of the equation by 4 to get x = 71.25
the angles are:
71.25
71.25
142.5
75
add them up and you get 360 degrees.
