Question

. In ∆ABC, m/A-40°, m/B-50° then write the names of sides of A ABC in ascending order.
explanation:-​

Answer 1

Answer:

BC AC AB

Step-by-step explanation:

The smallest angle has the smallest side opposite it

Answer 2

Step-by-step explanation:

Given:-

m/A=40°

m/B=50°

To find:-

m/C=?

Ascending order of Triangle ABC

Solution:-

In triangle ABC

A + B + C = 180° __(Angle additional property)

40° + 50° + C = 180°

90° + C = 180°

C = 180°-90°

C =90°

A < B < C __ (1)

Side opposite to greater angle is greater.

Therefore,

Side BC > Side AB > Side AC __(2)

Hence proved.
