Answer:
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
X + Y + Z = 180°
84° +(r +59)° +(r +51)° = 180°
2r +194 = 180 . . . . . . . . . divide by ° and simplify
2r = -14 . . . . . . . . . . subtract 194
r = -7
Then the measure of Y is ...
Y = (r +59)° = (-7 +59)°
Y = 52°

<em>Additional comment</em>
Z = 44°
Is there supposed to be a question or a picture with this ?
The answer is Side RQ corresponds to side QQ'. 100% sure and please feel free to ask more.
Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units
