Answer 2

Answer:

angle D is 80°

Step-by-step explanation:

as it is an isosceles triangle so 2 sides and angles are equal

if angle F is 180°-130°= 50°

then angle E also will be 180°-130° = 50°

we know that the sum of all the angles of triangle is 180°

50°+50°+x = 180°

100° + x = 180°

x= 180° - 100°

x = 80°
