Question

In each of the following cases , the measures of three angles are given. state which of the following groups from a triangle:
a) 65°,35°,80° b)45°,45°,60° c) 48°,43°,83°

please solve it ​

Answer 1

Answer:

how to check:

if we add the 3 angles, the result should be 180 degrees.

a)65,35,80

65+35+80=180

180=180

so, this forms a triangle.

b)45,45,60

45+45+60=150

150 is not equal to 180.

so this does not form a triangle.

c)48,43,83

48+43+83=174

174 is not equal to 180

so this doesn't form a triangle.

I hope you understand the concept...

Answer 2

Answer:

the sum of a triangle is 180

Step-by-step explanation:

a) 60°+35°+80°=180°

hence, it's a triangle.

b) 45°+45°+60°=150°

as we know that sum of triangle is 180°

so,it is not a triangle.

c) 48°+43°+83°=174°

so, it is not a triangle.
