Question

In a triangle DEF, if angle D = 35 degree, angle F = 100 degree, then angle E = ?

Answer 1

Answer:

45°

Step-by-step explanation:

we know that

total sum of angles of an triangle = 180°

now if one angle(D) = 35°

and another angle (F) = 100°

and angle (E) = ?

now we know,

D+F+E = 180°. (Put the values )

35° + 100° + E = 180°

135° + E = 180°

therefore, E = 180° - 135°

E = 45°

Answer 2

Answer:

E=45

Step-by-step explanation:

D+F+E=180

35+100+E=180. 135+E=180. E=180-135. E=45
