∘-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
∘
,85
∘
,40
∘
Sum of all three angles =190
∘
>180
∘
This set cannot form a triangle
(C) 65,85
∘
,30
∘
Sum of all three angles =180
∘
This set can form a triangle
(D) 45
∘
,45
∘
,80
∘
Sum of all three angles =170
∘
<180
∘
This set cannot form a triangle
