Question

An exterior angke of a triangle is 100 and one interito opposite angle is 45 .The othe two angles are

Answer 1

Step-by-step explanation:

By exterior angle property ,we know that

One exterior angle = sum of two interior opposite angles

So,100=45+ other angle

other angle= 55°

Now we have two angles.

By angle sum property ,sum of all angles in a triangle=180°

So,45°+55°+other angle= 180°

other angle = 90°

therefore the three angles of a triangle r 45°,55° and 90°
