Step-by-step explanation:

Triangle DEF, is a right angled triangle

angle D + angle E + angle F = 180°

90° + x + x = 180°

2x = 90°

x = 45°

Answer 2

Answer:

The given triangle is an isosceles triangle, and hence the base angles are equal and we already know the measure of the 3rd angle, hence the answer would be :-

90° + x + x = 180° ( Angle sum property of a triangle)

90° + 2x = 180°

2x = 180° - 90°

x = 90° / 2

x = 45°
