Answer:
Sum of all three angles =170
∘-180
Step-by-step explanation:
Solution
Correct option is
C
65
∘
,85
,30
Given set (A) 70
,90
,25
Sum of all three angles =185
>180
This set cannot form a triangle
(B) 65
,40
Sum of all three angles =190
(C) 65,85
Sum of all three angles =180
This set can form a triangle
(D) 45
,45
,80
<180
All those canbe expressed in the form of p/q, where q≠0 are rational
clearly A is rational
now 0.62 =62/100=31/50----its also rational
and 0.6 =6/10=3/5--- it's also rational
0.6π =(3/5)π, 3/5 is rational but π is irrational so overall it's irrational!
A,B&C are rational!

Yes you can just write them with denominator 1,
So 3 = 3/1 and -6 = -6/1.
