Question

quadrilateral has three acute angle of each measuring 75 °. find the measure of fourth angle

Answer 1

no sorry if they have 3 acute angle then forth angle is outside of the quadiratelal so it is not possible

Answer 2

let the fourth angle be x
Now, 75 + 75 + 75 + x = 360
= 225 + x = 360
= x = 360 - 225 = 135
therefore the fourth angle = 135 degree...
