Answer 1

Answer :

Given :

• A triangle is right angled at point A
• The measure of exterior angle is 145

To find :

• The measure of all angles

Solution :

As we know that the triangle ABC is right angled at point A . The measure of Angle BAC will be 90.

So now , by exterior angle property we have ,

= Angle BAC + Angle ABC = Angle BCX

= 90° + Angle ABC = 145°

= Angle ABC = 145 - 90

= Angle ABC = 55°

Now by angle sum property we get ,

= Angle ABC + Angle BAC + Angle BCA = 180°

= 55° + 90° + Angle BCA = 180°

= Angle BCA = 180 - 145

= Angle BCA = 35°
