Answer 1

Step-by-step explanation:

if one angle we say is 35 and the another is say 105 then find the last one

the rule of triangle is sum of all sides is 180

then let's take the third side as x

then 35+105+x=180

then 140+x=180

then x=180-140

that is 40 therefore we have proved that the sum of all sides of a triangle is 180
