Answer 2

Heya!

In triangle abc,

Angle B is equal to 105 degree

Angle c is equal to 50 degree

Angle a ?

Using angle some property,

All the sides of a triangle add up to 180 degee.

Therefore,

A+b+c = 180 degree

A+105+50 = 180 degree

A+155= 180 degree

A= 180 - 155

Therefore the measure of angle a is 25 degree
