Answer:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180
x=(180+30)/15=14
XYZ SIMILAR TO PDQ
Y=D=3*14+20=62
2 An angle in a regualr quadrilateral = 90 degrees
3. if exterior angle = 40 degrees then the number of sides in the plygon
= 360/40 = 9 sides
So its a nonagon.
How did you get 12? It should be 11 because 9+2=11.
