Step-by-step explanation:
As per diagram l∣∣m and n transversal.
We know that vertically opposite angles are equal
a=110
o
----(1)
d=85

----(2)
We also know that corresponding angles are equal.
a=b
d=c
=>a=b=110

Answer:
Answer
We know that
(a+b+c)
3
=(a
3
+b
3
+c
3
)+3[(a+b+c)(ab+ac+bc)−abc]
If (a+b+c)=0, then a
3
+b
3
+c
3
=3abc
Given, 3a+5b+4c=0
Here, a=3a, b=5b and c=4c
Now,
L.H.S =27a
3
+125b
3
+64c

=(3a)
3
+(5b)
3
+(4c)

=3(3a)(5b)(4c)
=180abc
=R.H.S
