This is an isosceles trapezoid find y
2 answers:
all the angles add up to 360 using the equation 180(s - 2)=d
d is the degree and s is the number of sides. it is an iscocles triangle so if you mirror the angles are the same
75+75=150
360-150=210
there are two angles left so divide by two
210/2=105
x and y equal 105
sum interior angles = 360°
(360 - 75 - 75) : 2 =
105°
