Question

Solve this proper please

Answer 1

Answer:

Lets see -

Step-by-step explanation:

In triangle ABC, applying angle sum

angle a + angle b + angle c = 180

50 + angle b + 90 = 180

angle b = 40

And in triangle BDF

Angle f + angle D + angle B = 180

angle f + 85 + 40 = 180

angle f = 55

Answer 2

Step-by-step explanation:

according to the property of triangle

x+y+z=180°

x+50°+85°=180

x+135°=180°

x=180°-135°

x=45°
