Question

Find the measure of Angle D.

Answer 1

Answer:

2x+6°=Angle D

angle D=2*8+6

angle D=22° (Ans)

Step-by-step explanation:

acc to the circle theorem angle formed by the radius is always 90°

and sum of all angles of a ∆ is always 180°

so, in ∆DEF

angleD+angleE+angleF=180°

2x+6+8x+4+90°=180°

10x+100=180

10x=180-100

x=80/10

x=8
