Answer:
m<U and m<S=60°
m<E and m<D=120°
Step-by-step explanation:
Remember,in a 4 sided polygon or quadrilateral,the sum of interior angles is 360°.
Therefore the sum of the measures of the angle must equal to 360°
m<U+m<S+m<E+m<D=360°
Substituting the expressions:
x+x+2x+2x=360
6x=360
x=60
Substituting the value of x in each expressions:
m<U=x=60°
m<S=x=60°
m<E=2x=2(60)=120°
m<D=2x=2(60)=120°
Therefore the measures of each angle is as follows:
