Answer:
(-7a-15)/3
Step-by-step explanation:
- 7 = 3/a ( x + 5)
open the bracket
-7 =3/a(x)+ 3/a(5)
-7 = 3x/a+ 15/a
l.c.m is a
-7= 3x+15/a
cross multiply
-7a = 3x+15
-7a-15 = 3x
(-7a-15)/3 = x
Answer:-1/12
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
No since they dont share x
Step-by-step explanation:
Sum of interior angle for a polygon = (n-2)180
It has 6 sides
=(6-2)180
=4*180
=720
Therefore, let the unknown interior angle =x
x+162+115+120+148+85=720
x+630=720
x=720-630
x=90^
