Answer 1

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

∘

,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
