Answer:
b = 
Step-by-step explanation:
Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.
Thus, to determine the value of b;
Sin θ = 
Sin b = 
= 
= 0.38462
⇒ b =
0.38462
= 22.6202
b = 
The measure of angle E (= b) is
.
=
I am also not able to solve thi s question
The answer is Angle Bisector.
I think this because if it were to be perpendicular the triangle would have to be congruent in SSS theorem or other.
I hope this helps!
