Find the measures of the numbered angles in the isosceles trapezoid.
torisob [31]

Answer:

Step-by-step explanation:

in an isocelles trapezoid, we have the properties:

the lower base angles are congruent

the upper base angles are congruent

we have an angle= 44

the angle #3= 44 because of the properties

so the lower base angles are equal and equal to 44

sum of the angles in trapezoid=360

360-(44*2)=360-88=272

upper base angles are equal

272/2=136

angle1=angle2=136
