Answer:
the missing angles are 47,° 77,° 56°
Step-by-step explanation:
(133)+(x+13)= 180° (angles on a straight line)
133+x+13= 180°
146+x= 180°
X= 180-146
X= 34°
FOR ANGLE A
2X+9= 2(34)+9= 68+9= 77°
FOR ANGLE C
X+13= 34+13= 47°
FOR ANGLE B
47+77+Y= 180 (SUM OF ANGLES IN A TRIANGLE)
124+Y= 180
Y= 180-124= 56°
Y= 56°
the missing angles are 47,° 77,° 56°

Answer:
the missing fence length = 2a² + 18
Step-by-step explanation:

? = (3a²+15a+9) - (a² + 15a -9) = 2a² + 18
